Local fix

Problem summary

• This APAR is only applicable to z/OS.
  On z/OS, when the environment variable JAVA_THREAD_MODEL is set
  to HEAVY, the JVM should spawn all threads as heavy weight
  threads. However, the JVM was failing to do so for the signal
  reporter thread.
  

Problem conclusion

• The JVM has been updated to correct this behavior.
  .
  This APAR will be fixed in the following Java Releases:
     7 R1 SR3 FP30  (7.1.3.30)
     8    SR2 FP10  (8.0.2.10)
  .
