What's new for IBM i 7.1

Read about new or significantly changed information for the IBM® Developer Kit for Java™ topic collection.

Start of changeThe following changes have been made to IBM Developer Kit for Java in IBM i 7.1:
  • The licensed program for IBM Developer Kit for Java is 5761-JV1.

    The licensed program is the same as in IBM i 6.1. However, the difference between IBM i 6.1 and IBM i 7.1 is that Java Developer Kit, which is also referred to as Classic Java, is no longer supported in IBM i 7.1. Classic Java support has been replaced by IBM Technology for Java.

    Customers still using Classic Java should refer to Considerations for using IBM Technology for Java Virtual Machine before upgrading to IBM Technology for Java.

  • The following topics have been updated to reflect the supported options of 5761-JV1 at IBM i 7.1:

  • PASE for i now enforces stack execution disable protection.

    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 7.1 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. See the IBM Center for Java Technology Developer Diagnostic GuideLink outside Information Center for additional information.
