This problem only applies to Java 6.0.1, Java 7, and Java 7.1.

Local fix

  • You may be able to avoid the problem by preventing the current
method being compiled. Otherwise, disable the JIT with -Xint,
however this will have a severe performance penalty.

Problem summary

  • The JIT uses an inappropriate C library string routine for the
type of string being processed.

Problem conclusion

  • The JIT has been corrected to use the appropriate C library
routine.
.
This APAR will be fixed in the following Java Releases:
