IV63630: PROGRAM CRASHES WITH ILLEGAL INSTRUCTION OR THROWS EXCEPTION in java.lang.UnsatisfiedLinkError ON X86

APAR status

• Closed as program error.

Error description

• Error Message: Windows_ExceptionCode: C000001D Illegal
  Instruction. The assembly code will show illegal instructions
  like xbegin or xend.
  Another symptom could be: Exception in
  thread "main" java.lang.UnsatisfiedLinkError
  java/util/concurrent/ConcurrentHashMap$Segment.tmPut(ILjava/util
  /concurrent/ConcurrentHashMap$HashEntry;)I
  .
  Stack Trace:
  .
  

Local fix

• The issue can be worked around by using the following JIT
  option:
  -Xjit:disableTLE,exclude={java/util/concurrent/ConcurrentLinkedQ
  ueue*,java/util/concurrent/ConcurrentHashMap*},dontinline={java/
  util/concurrent/ConcurrentLinkedQueue*,java/util/concurrent/Conc
  urrentHashMap*}
  

Problem summary

• The problem is caused by the JIT compiler generating a
  transactional memory instruction on a machine that doesn't
  support transactional memory
  

Problem conclusion

• JIT has been updated to check for the proper hardware support
  before the decision to generate transactional memory
  instructions
  .
  This APAR will be fixed in the following Java Releases:
     7 R1 SR2       (7.1.2.0)
  .
