IV29642: -XSCMINAOT AND -XSCMINJITDATA DO NOT HONOR EACH OTHER

APAR status

• Closed as program error.

Error description

• Error Message: Although sizes for -Xscminaot and -Xscminjitdata
  have been specified, the shared class cache runs out of space
  before the specified amount of aot or jitdata has been stored in
  the cache.
  .
  Stack Trace: N/A
  .
  

Local fix

Problem summary

• Minimum space reserved for AOT and JIT data in shared class
  cache specified by -Xscminaot and -Xscminjitdata options
  respectively is not honored by JVM when both options are
  specified.
  In presence of both the options, JVM incorrectly calculates the
  free bytes available in shared class cache.
  

Problem conclusion

• This defect will be fixed in:
  7.0.0 SR3
  6.0.1 SR4
  .
  The JVM has been updated to correctly reserve the minimum space
  for AOT and JIT data by -Xscminaot and -Xscminjitdata options
  respectively, and to correctly calculate free bytes in the
  shared class cache.
  

Temporary fix
