Notes

Default timeouts have changed for FTP URL handler Timeouts used by the FTP URL protocol handler have been changed from infinite to 5 minutes. This will result in an IOException from connect and read operations if the FTP server is unresponsive. For example, new URL("ftp://example.com").openStream().read(), will fail with java.net.SocketTimeoutException in case a connection or reading could not be completed within 5 minutes.

To revert this behaviour to that of previous releases, the following system properties may be used, sun.net.client.defaultReadTimeout=0, sun.net.client.defaultConnectTimeout=0

Demo references in Solaris install documentation Demos were removed from package tar.Z bundle. There is a separate Demos&Samples bundle beginning with 7u2 b08 and 6u32 b04, but Solaris patches still contain SUNWj7dmo/SUNWj6dmo. The 64 bit packages are SUNWj7dmx/SUNWj6dmx

Demo packages remain in the existing Solaris patches; however, just because they are there doesn’t mean that they are installed. They will be patched only if the end user has them installed on the system.

The link above is to the Solaris OS Install Directions for the JDK. The SUNWj7dmx package is mentioned in the tar.Z portion of the directions. This is confusing to some as, according to the cited bug, the SUNWj7dmx package shouldn’t be part of the tar.Z bundle.

Certificate Changes

Remove revoked Swisscom root certificate “swisscomrootevca2” 

One Swisscom root certificate has been revoked by Swisscom and has been removed:

Swisscom Root EV CA 2
alias: "swisscomrootevca2 [jdk]"
DN: CN=Swisscom Root EV CA 2, OU=Digital Certificate Services, O=Swisscom, C=ch

New Features

New Security property to control crypto policyThis release introduces a new feature whereby the JCE jurisdiction policy files used by the JDK can be controlled via a new Security property. In older releases, JCE jurisdiction files had to be downloaded and installed separately to allow unlimited cryptography to be used by the JDK. The download and install steps are no longer necessary. To enable unlimited cryptography, one can use the new crypto.policy Security property. If the new Security property (crypto.policy) is set in the java.security file, or has been set dynamically by using the Security.setProperty() call before the JCE framework has been initialized, that setting will be honored. By default, the property will be undefined. If the property is undefined and the legacy JCE jurisdiction files don’t exist in the legacy lib/security directory, then the default cryptographic level will remain at ‘limited’. To configure the JDK to use unlimited cryptography, set the crypto.policy to a value of ‘unlimited’. See the notes in the java.security file shipping with this release for more information.

Note: On Solaris, it’s recommended that you remove the old SVR4 packages before installing the new JDK updates. If an SVR4 based upgrade (without uninstalling the old packages) is being done on a JDK release earlier than 6u131, 7u121, 8u111, then you should set the new crypto.policy Security property in the java.security file.

Because the old JCE jurisdiction files are left in <java-home>/lib/security, they may not meet the latest security JAR signing standards, which were refreshed in 6u131, 7u121, 8u111, and later updates. An exception similar to the following might be seen if the old files are used:

Caused by: java.lang.SecurityException: Jurisdiction policy files are not signed by trusted signers! at javax.crypto.JceSecurity.loadPolicies(JceSecurity.java:593) at javax.crypto.JceSecurity.setupJurisdictionPolicies(JceSecurity.java:524)

Changes

Refactor existing providers to refer to the same constants for default values for key length Two important changes have been made for this issue:

1. A new system property has been introduced that allows users to configure the default key size used by the JDK provider implementations of KeyPairGenerator and AlgorithmParameterGenerator. This property is named “jdk.security.defaultKeySize” and the value of this property is a list of comma-separated entries. Each entry consists of a case-insensitive algorithm name and the corresponding default key size (in decimal) separated by “:”. In addition, white space is ignored.

By default, this property will not have a value, and JDK providers will use their own default values. Entries containing an unrecognized algorithm name will be ignored. If the specified default key size is not a parseable decimal integer, that entry will be ignored as well.

2. The DSA KeyPairGenerator implementation of the SUN provider no longer implements java.security.interfaces.DSAKeyPairGenerator. Applications which cast the SUN provider’s DSA KeyPairGenerator object to a java.security.interfaces.DSAKeyPairGenerator can set the system property “jdk.security.legacyDSAKeyPairGenerator”. If the value of this property is “true”, the SUN provider will return a DSA KeyPairGenerator object which implements the java.security.interfaces.DSAKeyPairGenerator interface. This legacy implementation will use the same default value as specified by the javadoc in the interface.

By default, this property will not have a value, and the SUN provider will return a DSA KeyPairGenerator object which does not implement the forementioned interface and thus can determine its own provider-specific default value as stated in the java.security.KeyPairGenerator class or by the “jdk.security.defaultKeySize” system property if set.

Collections use serialization filter to limit array sizes

Deserialization of certain collection instances will cause arrays to be allocated. The ObjectInputFilter.checkInput() method is now called prior to allocation of these arrays. Deserializing instances of ArrayDeque, ArrayList, IdentityHashMap, PriorityQueue, java.util.concurrent.CopyOnWriteArrayList, and the immutable collections (as returned by List.of, Set.of, and Map.of) will call checkInput() with a FilterInfo instance whose style=”font-family: Courier New;”>serialClass() method returns Object[].class. Deserializing instances of HashMap, HashSet, Hashtable, and Properties will call checkInput() with a FilterInfo instance whose serialClass() method returns Map.Entry[].class. In both cases, the FilterInfo.arrayLength() method will return the actual length of the array to be allocated. The exact circumstances under which the serialization filter is called, and with what information, is subject to change in future releases.

keytool now prints warnings when reading or generating certificates/certificate requests/CRLs using weak algorithms 

With one exception, keytool will always print a warning if the certificate, certificate request, or CRL it is parsing, verifying, or generating is using a weak algorithm or key. When a certificate is from an existing TrustedCertificateEntry, either in the keystore directly operated on or in the cacerts keystore when the -trustcacerts option is specified for the -importcert command, keytool will not print a warning if it is signed with a weak signature algorithm. For example, suppose the file cert contains a CA certificate signed with a weak signature algorithm, keytool -printcert -file cert and keytool -importcert -file cert -alias ca -keystore ks will print out a warning, but after the last command imports it into the keystore, keytool -list -alias ca -keystore ks will not show a warning anymore.

Precisely, an algorithm or a key is weak if it matches the value of the jdk.certpath.disabledAlgorithms security property defined in the conf/security/java.security file.

New defaults for DSA keys in jarsigner and keytool For DSA keys, the default signature algorithm for keytool and jarsigner has changed from SHA1withDSA to SHA256withDSA and the default key size for keytool has changed from 1024 bits to 2048 bits.

Users wishing to revert to the previous behavior can use the -sigalg option of keytool and jarsigner and specify SHA1withDSA and the -keysize option of keytool and specify 1024.

There are a few potential compatibility risks associated with this change:

  1. If you have a script that uses the default key size of keytool to generate a DSA keypair but then subsequently specifies a specific signature algorithm, ex:

    keytool -genkeypair -keyalg DSA -keystore keystore -alias mykey ...
    keytool -certreq -sigalg SHA1withDSA -keystore keystore -alias mykey ...
    it will fail with one of the following exceptions, because the new 2048-bit keysize default is too strong for SHA1withDSA:

    keytool
    error: java.security.InvalidKeyException: The security strength of
    SHA-1 digest algorithm is not sufficient for this key size
    keytool error: java.security.InvalidKeyException: DSA key must be at most 1024 bits
    The workaround is to remove the -sigalg option and use the stronger SHA256withDSA default or, at your own risk, use the -keysize option of keytool to specify a smaller key size (1024).

  2. If you use jarsigner to sign JARs with the new defaults, previous versions (than this release) of JDK 6 and 7 do not support the stronger defaults and will not be able to verify the JAR. jarsigner -verify on an earlier release of JDK 6 or 7 will output the following error:

    jar is unsigned. (signatures missing or not parsable)
    If you add -J-Djava.security.debug=jar to the jarsigner command line, the cause will be output:

    jar: processEntry caught: java.security.NoSuchAlgorithmException: SHA256withDSA Signature not available
    If compatibility with earlier releases is important, you can, at your own risk, use the -sigalg option of jarsigner and specify the weaker SHA1withDSA algorithm.

  3. If you use a PKCS11 keystore, the SunPKCS11 provider does not support the SHA256withDSA algorithm. jarsigner and some keytool commands may fail with the following exception if PKCS11 is specified with the -storetype option, ex:

    keytool
    error: java.security.InvalidKeyException: No installed provider
    supports this key: sun.security.pkcs11.P11Key$P11PrivateKey
    A similar error may occur if you are using NSS with the SunPKCS11 provider. The workaround is to use the -sigalg option of keytool and specify SHA1withDSA.

Add warnings to keytool when using JKS and JCEKS When keytool is operating on a JKS or JCEKS keystore, a warning may be shown that the keystore uses a proprietary format and migrating to PKCS12 is recommended. The keytool’s -importkeystore command is also updated so that it can convert a keystore from one type to another if the source and destination point to the same file.

keytool now prints out information of a certificate’s public key 

Keytool now prints out the key algorithm and key size of a certificate’s public key, in the form of “Subject Public Key Algorithm: <size>-bit RSA key", where <size> is the key size in bits (ex: 2048).
