IV77910: CRASH, ERROR, OR UNDEFINED BEHAVIOR ON AIX
Closed as program error.
Error Message: The error will vary and can include crashes, Java exceptions, and other undefined behavior. This issue only affects the AIX platform. . Stack Trace: N/A .
Set the environment variable "TR_DisableTrapPeephole" to 1 in order to disable this optimization.
The JIT compiler performs a micro-optimization on AIX that reorders certain instructions to speed up a memory access. In very rare cases, this optimization incorrectly reorders certain instructions, causing the program to read from an invalid memory location.
The JIT compiler was fixed to prevent the micro-optimization from incorrectly reordering instructions in certain cases. . This APAR will be fixed in the following Java Releases: 8 SR2 (18.104.22.168) 6 R1 SR8 FP15 (22.214.171.124) 7 R1 SR3 FP20 (126.96.36.199) 6 SR16 FP15 (188.8.131.52) 7 SR9 FP20 (184.108.40.206) .
