    To improve system security, the default behavior for PASE for i programs has changed so that instructions run from memory areas (stack, heap, and shared memory) of a process are blocked. IBM Technology for Java JIT generated code is created in memory areas. A PASE for i program that calls the JNI_CreateJavaVM() API needs to follow the instructions in PASE for i What's new for IBM i 7.2 to mark the program as needing to allow program execution from memory areas.

  • Additional documentation about IBM Technology for Java can be found on the IBM Center for Java Technology Developer Web site.

    The IBM Technology for Java JVM is based on the AIX® version of the IBM Center for Java Technology Developer Kit. The IBM Center for Java Technology Developer Kits have common documentation that applies to all supported platforms. Within that common documentation there exits sections that document platform differences. When IBM i platform documentation does not exit the AIX version of the documentation should be used.
