PM40017: MEMORY LEAK OF CHARACTERS CCVT IN SETUPCARDINFORMATION METHOD OF IBMJCECCA PROVIDER

APAR status

• Closed as program error.

Error description

• Error Message: The ebcdic string "CCVT" is leaked each time the
  method
  Java_com_ibm_crypto_hdwrCCA_provider_HIKM_SetupCardInformation
  is called inside the z/OS Java hardware cryptography provider (
  IBMJCECCA ).
  On systems where the IBMJCECCA provider is installed the leak
  may result in native memory problems. When combined with the
  Language Environment malloc header, this leak is 12 bytes in
  size. In a HeapPool environment, the leak may manifest as large
  numbers of HeapPool extents for the size containing these
  entries.
  KEYWORDS:
  ibmjcecca.jar hdwrCCA SetupCardInformation java memory leak
  .
  FIXED IN JAVA 5 UNDER APAR PM27331
  

Local fix

• If the 4 byte native memory leak is affecting your system, you
  can revert to the Java software Cryptography Extension provider
  ( IBMJCE ).
  NOTE: This leak does NOT affect Java Heap storage. This is a
  leak within Language Environment heap memory.
  

Problem summary

• A 4 byte memory leak occurs in the method
  Java_com_ibm_crypto_hdwrCCA_provider_HIKM_SetupCardInformation()
  of the IBMJCECCA provider on z/OS.
  

Problem conclusion

• This defect will be fixed in:
  6.0.0 SR10
  .
  The 4 bytes of memory are no longer dynamically allocated. The
  memory leak will no longer occur.
  .
  To obtain the fix:
  Install build 20110216 or later
  

Temporary fix
