IBM SDK, Java Technology Edition, Version 7 Release 1: Current news
Support information for IBM® SDK, Java™ Technology Edition, Version 7 Release 1 that is not available in the user documentation.
The documentation to support this release is available in the online product documentation.
InstallAnywhere installation packages
There are two types of InstallAnywhere packages:
Installing these packages also configures your system, for example by setting environment variables. You must use a user account with ROOT authority to install this type of package.
Installing these packages extracts the files to your system, but does not perform any configuration. This type of package does not require ROOT authority to complete the installation.
Supplementary information is available for the following updates:
For information about the daylight saving time changes included in this release, see Olson time zone updates. Later updates can by applied using the IBM Time Zone Update Utility for Java (JTZU).
To compare the IBM SDK functionality with Oracle build levels at each service refresh level, see Comparative Oracle build levels.
You can download the SDK from developerWorks.
Service refresh 3 fix pack 10 (July 2015)
Partial fix for change in behavior for -Xshareclasses:destroyAll
In service refresh 2 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 3 (May 2015)
DumpControlMXBean visible in JConsole
The DumpControlMXBean is unintentionally visible in JConsole. Do not use this MXBean to create heap, system, or Java dumps. Instead, use the Health Center tool as described in Triggering Dumps.
Service refresh 2 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.
When you download and install packages for this release, you can choose a language in which to review and accept the license. On Windows (Installshied) packages, and AIX® or Linux (InstallAnywhere) archive packages, there is no option to review the license in Lithuanian even though a Lithuanian license exists in the package. You must choose an alternative language during installation and then review the contents of the Lithuanian license, which can be found in the docs/lt directory.
Co-existence of releases
IBM SDK, Java Technology Edition Version 7 Release 1 can co-exist with IBM SDK, Java Technology Edition Version 7 on the same Windows operating system. However, if the first installation is removed, the Windows registry is corrupted and the following error is seen when you run the java -version command:
Error: Failed reading value of registry key:
Software\IBM\Java2 Runtime Environment\CurrentVersion
Error: could not find java.dll
Error: Could not find Java SE Runtime Environment.
This problem occurs when the second installation is installed as the system or non-system JVM. In this situation, you can obtain version information by specifying the full installation path when you run the java -version command.
