IV13764: CRASH IN THE JIT COMPILER WHILE COMPILING A METHOD
Closed as program error.
Error Message: Unhandled exception with a vmstate=0x5ff06 . Stack Trace: TR_SetMonitorStateOnBlockEntry::set TR_CodeGenerator::doInstructionSelection TR_CodeGenerator::generateCodePhase1??????????? TR_CodeGenrattor::generateCode .
N/A. There is no known workaround for the problem at this time because the code paths in the compiler need to run and cannot be disabled.
The problem is related to the way the compiler propagates information about locks within the method being compiled. The problem is in turn caused by how older Javac (in particular 1.3.1) generates exception ranges compared to newer Javac (1.4.2 and above). The older javacs include 'return' bytecode within the exception range for synchronized blocks whereas newer javacs exclude 'return' bytecodes from the range. This inclusion causes problems for the JIT compiler during the identification of live locks in the method.
This defect will be fixed in: 6.0.0 SR11 6.0.1 SR2 7.0.0 SR1 . The JIT compiler has been updated to workaround the scenario when 'return' bytecodes could be included in exception ranges and propagate the information about live locks correctly.
