IV26343: JIT INLINE GUARD ELIMINATION CAUSING FAILURES
Closed as program error.
Error Message: An exception occurs while executing a JIT-compiled Java method that gets an incorrect object address due to executing the inlined code of the wrong method. The actual failure symptoms may vary depending on what incorrect inlined method gets executed. . Stack Trace: N/A .
The problem is caused by a internal JIT optimization that incorrectly eliminates inline guards in a particular scenario in which class hierarchy optimizations is disabled, but the inline guard should not be eliminated when class hierarchy optimizations is disabled. In very rare cases where the JIT compiler fails compilation of the method multiple times due to class hierarchy table changing, this problem can occur. It could also occur if a user explicitly uses the -Xjit:disableCHOpts option.
This defect will be fixed in: 6.0.0 SR11 6.0.1 SR2 FP1 7.0.0 SR2 . The JIT compiler has been updated to ensure that the inline guard does not get eliminated when class hierarchy optimizations is disabled.
