Local fix

  • 



Problem summary


    

  • A NULL check for a JIT internal object was missing hence a
de-reference caused a segmentation error.

    



Problem conclusion


    

  • The NULL check was added to prevent de-referencing the JIT
internal object if it wasn't instantiated.
.
This APAR will be fixed in the following Java Releases:
   7 R1 SR3 FP10  (7.1.3.10)
