IZ69786: VARIOUS CRASHES OR EXCEPTIONS IN APPLICATION
Closed as program error.
Error Message: Various types of crashes or exceptions reported by the JVM during application runs. . Stack Trace: N/A .
-Xjit:disableLookahead will work around the problem. Please not however, that disabling this optimization may impact performance of the application.
The problem is due to incorrect information generated by the JIT compiler about an array field declared in a class. The JIT compiler assumes that there is only a constant length allocation for this field in the class constructor and ignores other stores to this field. This erroneous information is then used by other optimizations (like constant propagation to do constant folding of the arraylength) and this results in unexpected program behavior.
This defect will be fixed in: 6.0.0 SR8 5.0.0 SR11 FP2 . The JIT compiler has been updated so that such incorrect information is not generated for array fields. . To obtain the fix: Install build 20100210 or later
