There are updates made to the IBM® 64-bit Runtime Environment for z/TPF, Java™ Technology Edition, Version 8 to address various product security vulnerabilities.  For more information, see the security bulletin. The updates also include z/TPF-specific changes to enable the JVM shutdown hook, ujvm_jvm_shutdown_hook(), for Java 8 as well as making certain network methods externally visible in order to better facilitate using a Kafka producer with Kerberos enabled.

There are additional z/TPF updates provided with APAR PJ46945. Notably, new pre- and post- dump agent hooks have been added to the JVM user exit routines (UJVM) in support of low priority system dumps. Specify the property -Dcom.ibm.tpf.jvm.lowPrioritySysDumps to enable low priority system dumps.

Download and install the PJ46945_ibm-java-jre-8.0-7.20 package from the z/TPF support for IBM Semeru Runtimes and IBM Java SDK download page. This update, and associated changes made for APAR PJ46945, replaces the runtime environment provided with APAR PJ46780.
