Yes, that's exactly my question. I couldn't find an easy way to turn off this compressed-ptr optimization. It's a little bit surprising me. :-)

Did you check that it works on 64 bit mode with uncomressed references. I remember some time ago there were issues like hard coded compressed references used in JIT (or probably somewhere else) in 64bit mode. Best regards, Aleksey.
