Local fix
-Xjit:disableLoopAliasRefiner
Problem summary
The JIT occasionally performed an incorrect optimization on a program having logic that does different typecasts on the same object to different array types on different paths within a loop. In such programs, the Loop Alias Refiner optimization could transform the loop in such a way that it used the wrong array types on some paths.
Problem conclusion
The Loop Alias Refiner optimization was fixed to detect the problematic situation and avoid performing the incorrect transformation. The problem was introduced in Java 8 GA and has been fixed in Java 8 SR2. . This APAR will be fixed in the following Java Releases: 8 SR1 FP10 (8.0.1.10) .
