IV09350: JNI DEMO APPLICATIONS NOT WORKING WITH 64-BIT ZOS SDK

APAR status

• Closed as program error.

Error description

• Error Message: The JNI Demo Application is failed to compile in
  64-bit zOS JDK 6 build.
  The following are the steps to compile a JNI demo file:
  export PATH=<JAVA_HOME>/bin:$PATH
  export JAVA_HOME=<JAVA_HOME>
  cd <JAVA_HOME>/demo/jni/InvocationAPI/c
  <JAVA_HOME>/demo/jni/InvocationAPI/c>./make.sh

Local fix

• Modify the Makefile to include the compiler and linker option -W
  "c,langlvl(extended),lp64"
  

Problem summary

• The 31-bit and 64-bit SDK uses the same JNI demo makefiles.
  Hence the 64-bit compile option <OSB>-W
  "c,langlvl(extended),lp64"<CSB> is not included in the Makefile.
  and it resulted in the link error while linking it with 64-bit
  object modules.
  

Problem conclusion

• This defect will be fixed in:
  6.0.0 SR10
  6.0.1 SR1
  7.0.0 SR1
  .
  Modified the JDK to use separate header files with compiler and
  linker flags for 31-bit and 64-bit zOS SDK.
  .
  To obtain the fix:
  Install build 20111022 or later
  

Temporary fix
