        The problem happens on a deoptimization between a jsr bytecode and a ret bytecode. The compiler always stores the bci to return to (a local variable) in the debug information it generates as a constant 32 bit integer but the interpreter loads it from the local variables in the ret bytecode as a 32 bit or 64 bit integer depending on whether the VM is 32 or 64 bits.

        Found during JRTS 2.2u1 testing.
