NonStop Server for Java 7.0 Update1
NonStop Server for Java 7.0 Update1 includes functionality, enhancements, and defect fixes
equivalent to Oracle releases up to and including Java 7 U25. It includes security fixes released
by Oracle up to October 2013.
NonStop Server for Java 7.0 Update1 contains these new features:
• SecureRandom number generation enhancement
An improved method for random number generation is introduced which reduces the processing
time taken to generate the first random number in a Java application. A new command line
option is introduced to enable this SecureRandom number generation method.
• JVM Data segment allocation
Two new command line options, one for 32-bit JDK and one for 64-bit JDK, are introduced
to customize the JVM heap size depending upon the application need.
◦ 32-bit JDK
Use the new option to specify the maximum JVM heap size expected for the application.
This can free up to 192MB of virtual memory for the application compared to earlier
NSJ7 release.
◦ 64-bit JDK
Use the new option to specify the initial JVM heap size expected for the application.
Using this option, one can avoid costly segment resize in the middle of the application
execution.
• VirtualMachine.list() improvement
VirtualMachine.list() has been enhanced to return the list of Java processes running in the
target machine.
• Handling large Garbage Collection (GC) log files
◦ A new command line option is introduced to support GC log file rotation.
For more information on these features, see NonStop Server for Java 7.0 Programmer’s Reference.

HP JToolKit for NonStop Server for Java 7.0 and 6.0
Beginning with this RVU, all the pure Java data conversion methods (those which do not have
native dependency) are available and usable off-platform. A Pathway server or ddl2java
generated I/O class can directly call the data conversion methods from within a non-NonStop
platform such as Windows, UNIX, Linux and Solaris.
Migration Considerations
None.
