Service refresh 10 fix pack 20 (Jan 2018)
Out of memory exceptions when running applications with compressed references enabled
The Oracle CPU for January contains an update for CVE-2018-2582 to fix vulnerabilities in the Hotspot virtual machine (VM) that might be exploited by Java web start applications and applets. Fixes are also applied for the OpenJ9 virtual machine. The fix increases the amount of low memory used for VMs that use compressed references. Customers who are running close to the maximum amount of allowed 32-bit memory might experience out of memory exceptions. A possible workaround is to use the -Xmcrs option to secure space in the lowest 4GB memory area for any native classes, monitors, and threads that are used by compressed references.
For more information about this option, see -Xmcrs.
Service refresh 10 fix pack 10 (October 2017)
Support for z/OS v2.3
This update includes support for z/OS v2.3.
Service refresh 10 fix pack 1 (February 2017)
Security vulnerability CVE-2016-2183
A further fix is added to mitigate against this vulnerability, which is described here. (APAR IV93288)
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 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 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.
