Please review those changes fixing the error message for NullPointerExceptions thrown by checkcast.

Without the fix:
java.lang.NullPointerException: There cannot be a NullPointerException at bci 23 of method void NPECheckcastTest.main(java.lang.String[])

With the fix:
java.lang.NullPointerException: Cannot cast to null-free type "QNPECheckcastTest$C1;" because "<local2\>" is null

Thank you,
