Service refresh 9 fix pack 10 (July 2015)
Partial fix for change in behavior for -Xshareclasses:destroyAll
In service refresh 8 fix pack 10 a behavior change was reported for this option on z/OS platforms. See Change in behavior for -Xshareclasses:destroyAll.
Following a fix for the 64-bit JVM, the problem remains only on the 31-bit JVM. When the destroyAll option is invoked from a 31-bit JVM, 64-bit caches are not destroyed. The following message is displayed:
JVMSHRC735I Use a 64-bit JVM to perform the requested operation on the 64-bit shared cache \"cachename\" as the 31-bit JVM cannot verify that the shared memory was created by the JVM
Service refresh 9 fix pack 1 (June 2015)
Logjam security vulnerability
A potential weakness is exposed with DH and DHE cipher suites that relates to the Logjam security vulnerability. A fix is provided to address this issue. For more information, see IBM SDK, Java Technology Edition: Fix packs to address the Logjam security vulnerability (CVE-2015-4000)
Service refresh 8 fix pack 10 (February 2015)

Change in behavior for -Xshareclasses:destroyAll
Due to a current issue on z/OS, when the destroyAll option is invoked from a 31-bit Java virtual machine (JVM), 64-bit caches are not removed. Similarly, when the destroyAll option is invoked from a 64-bit JVM, 31-bit caches are not removed. The following message is displayed:
JVMSHRC735I: Use a nn-bit JVM to perform the requested operation on the nn-bit shared cache \"cachename\" as the nn-bit JVM cannot verify that the shared memory was created by the JVM.
Service refresh 6 fix pack 1 (January 2014)
Default behaviour change when running unsigned or self-signed applets
Unsigned or self-signed applets no longer run by default because the security settings are changed to high. If you want to run unsigned or self-signed applets, you must change the security settings to medium. You can make this change in the Java Control Panel. Select the Security tab and move the slider to adjust the security level. This behavior change is not applicable to z/OS® or Linux on system Z platforms.
Service refresh 6 (October 2013)
Support for Windows Server 2012 R2
From this release of the SDK, Windows Server 2012 R2 is a supported environment on x86-64 platforms. The supported environments page in the user documentation is currently incorrect and will be corrected.
Service refresh 4 fix pack 2 (May 2013)
This fix pack includes a change to the default value for the RMI property java.rmi.server.useCodebaseOnly from false to true, which might cause unexpected errors for applications that use RMI. For more information, see http://docs.oracle.com/javase/7/docs/technotes/guides/rmi/enhancements-7.html.
On Windows, improvements are made to the way that Runtime.exec decodes command strings. However, applications specifying commands that contain spaces in the program name, or that use quotation marks incorrectly, might fail to start. For more information, including guidance on resolving problems, see http://www.oracle.com/technetwork/java/javase/7u21-relnotes-1932873.html#jaruntime.
Service refresh 4 fix pack 1 (April 2013)
This fix pack contains a security fix for the Oracle security vulnerability,CVE-2013-0169. For any further security fixes in this release, see Security alerts.
Service refresh 3 (November 2012)
PKCS11 security provider
A new library is available that allows the IBMPKCS11Impl provider to run on the Linux AMD64 platform.
IBM SDK for Java Version 7 initial release (September 2011)
The SDK is functionally equivalent to the Oracle FCS version of Java 7 b147 for all distributions except Solaris, which is b148.
The z/OS® 31-bit and 64-bit SDKs are supported on z/OS 1.13.
