Java HotSpot VM Equivalents to _JIT_ARGS Environment Variables
Most _JIT_ARGS environment variables are internal debugging options only and have no corresponding Java HotSpot VM options. Most simply turn off some form of optimization which may have caused instability when first introduced and could be used by the internal testing group to track down problems.
