        The same is reproducible on Solaris, 1.3.1_02 and the server compiler only
        (works fine with client compiler and in the interpreted mode). Not reproducible with 1.4. HP's customer is actively waiting for a fix for 1.3.1. I wasn't able to locate the code that fixed this problem. Need assistance from the Hotspot team and the CTE.
