New Features and Changes

SSLv3 is disabled by default

Starting with JDK 7u75 release, the SSLv3 protocol (Secure Socket Layer) has been deactivated and is not available by default. See the java.security.Security property jdk.tls.disabledAlgorithms in <JRE_HOME>/lib/security/java.security file.

If SSLv3 is absolutely required, the protocol can be reactivated by removing "SSLv3" from the jdk.tls.disabledAlgorithms property in the java.security file or by dynamically setting this Security property to "true" before JSSE is initialized.

It should be noted that SSLv3 is obsolete and should no longer be used.

  • Enable SSLv3 protocol on deploy level: edit the deployment.properties file and add the following:
