IV72102: ON Z/OS, A 64-BIT JVM DOES NOT DELETE SHARED CLASS CACHE CREATED BY 31-BIT JVM

APAR status

• Closed as program error.

Error description

• Error Message: JVMSHRC735I Use a 32-bit JVM to perform the
  requested operation on the 32-bit shared cache <cache name> as
  the 64-bit JVM cannot verify that the shared memory was created
  by the JVM
  .
  Stack Trace: N/A
  .
  

Local fix

• Use a 31-bit JVM to destroy the shared class cache created by a
  31-bit JVM.
  

Problem summary

• This problem occurs on z/OS when a 64-bit JVM attempts to
  destroy a shared class cache created by a 31-bit JVM. In such
  case, the JVM fails to verify that the associated shared memory
  was created by a JVM of another addressing mode, causing it to
  exit without destroying the cache.
  

Problem conclusion

• JVM has been updated such that a 64-bit JVM can now recognize
  and verify that the shared memory associated with a shared class
  cache was created by a 31-bit JVM.
