PH13539: JVM received zero divide error as COBOL v5 enables IEEE divide-by-zero

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• COBOL v5 and later enable IEEE floating point divide-by-zero
  exceptions. Java (C/C++) semantics expect a divide-by-zero to
  result in a positive or negative infinity rather than an
  exception, but when run with COBOL active in the enclave a zero
  divide at JVM routine helperDoubleDivideDouble+0x4 produces an
  exception.
  

Local fix

• See PI23475 and install as USRHDLR(,IGZXDIVZ) if you continue to
  see the exception.

  ****************************************************************
  
  Users installed the IGZXDIVZ sample available with PI23475,
  and then ran Java application with JVM -XCEEHDLR or
  -Xsignal:userConditionHandler=percolate. When
  CEE3224S(IEEE division--by--zero exception)
  occurred, the application terminated with Java 'Unhandled
  exception'.
  
  The -XCEEHDLR option converted the Language Environment
  condition into Java ConditionException. The exception was then
  handled by JAVA, which terminated the application, instead of
  passing to the user handler in IGZXDIVZ.
  -Xsignal:userConditionHandler=percolate led
  to the similar results.
  
  Refer also to PI23475.

Problem conclusion

• Use USRHDLR(,IGZXDIVZ) when running the program. The usage
  instructions in the IGZXDIVZ sample has been updated.
