PI23475: JVM RECEIVED ZERO DIVIDE ERROR AS COBOL V5 SETS IEEE DIVIDE-BY-ZERO MASK

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• COBOL version 5 sets floating point divide-by-zero mask on.
  Expected zero divide in JVM routine
  helperDoubleDivideDouble+0x4 fails since the program mask is
  set on in COBOL

Problem summary

• ****************************************************************
  * USERS AFFECTED: Version 5 Enterprise COBOL users using OO    *
  *                 COBOL, or interacting with other programs    *
  *                 that expect an IEEE divide by zero operation *
  *                 to result in infinity.                       *
  *                                                              *
  ****************************************************************
  * PROBLEM DESCRIPTION: Starting with version 5, the COBOL      *
  *                      runtime enables the IEEE divide-by-zero *
  *                      exception mask in order to catch and    *
  *                      diagnose divide by zero operations.     *
  *                      This may lead to LE message CEE3224S to *
  *                      be produced in other non-COBOL programs *
  *                      running in the same enclave, where such *
  *                      programs expect the divide operation    *
  *                      to return infinity instead.             *
  *                                                              *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  Other non-COBOL IEEE programs may terminate with LE condition
  CEE3224S due to the COBOL runtime enabling the IEEE
  divide-by-zero exception mask.
  

Problem conclusion

• Apply provided service.
  Follow the instructions in the IGZXDIVZ sample installed by this
  PTF to compile and link the condition handler into the SCEERUN
  dataset, and use the LE runtime option USRHDLR(IGZXDIVZ) with
  the affected application.
