IJ46192: CRASH WHEN USING IBMJCEPLUS WITH BALANCED GC

APAR status

• Closed as program error.

Error description

• Error Message: The JVM terminates with GPF when using the
  IBMJCEPlus provider in combination with the balanced gc policy
  .
  Stack Trace: The native stack as seen in the javacore contains
  either
  Fast_com_ibm_crypto_plus_provider_icc_NativeInterface_CIPHER_enc
  ryptUpdate
  or
  Fast_com_ibm_crypto_plus_provider_icc_NativeInterface_DIGEST_upd
  ate
  .
  

Local fix

• The problem can be avoided by using the gencon gc policy or
  other gc policies which do not use arraylets, or by using the
  following JVM command line option
  -Xjit:disableDirectToJNI
  Note that there can be at most one Xjit option on the command
  line so if there is an existing Xjit option already in use the
  above will need to be merged with it by appending
  ",disableDirectToJNI" to the end.
  

Problem summary

• The Fast_com_ibm_* functions provide an optimised pathway for
  accessing the security provider. In these methods the code for
  handling arraylets in order to support the balanced gc policy
  contained an error that resulted in the crash.
  

Problem conclusion

• The code in the JNI methods has been corrected.
