I'm using
jruby 1.7.11 (1.9.3p392) 2014-02-24 86339bb on Java HotSpot(TM) Client VM 1.7.0_10-b18 [Windows XP-x86]

I try to run
jruby -Xcompile.mode=JIT -Xjit.debug=true -Xjit.codeCache=c:\tmp test.rb
and an excpetion will be thrown

2014-03-26T21:51:33.000+01:00: JITCompiler: writing jitted code to to c:\tmp\rubyjit\FILE_4F37991FE5C3D20BF1325EE061298740151BB2D6.class

I think the reason is, my cached jit classes doesn't contain a JITCompiler.CLASS_METHOD_DELIMITER as expected by the BacktraceData.

I guess this one can be closed.
"jit.codeCache" is deprecated in 9k and (as far as I can see) does nothing nowadays.
