Local fix

  • N/A

Problem summary

  • A crash in JIT compiled Java code can happen if a global
register dependency is missing, causing the compiler to not
preserve a value which is later needed, resulting it in being
overwritten. The problem was observed to have happened shortly
after a STOC instruction which is infrequently generated on the
z Systems platform.

Problem conclusion

  • The JIT compiler has been updated to avoid the problem by
disabling the use of the STOC instructions.
