Using the following config options in my .jrubyrc:

invokedynamic.all=true
compile.invokedynamic=true
compile.fastest=true
compile.mode=FORCE
objectspace.enabled=false
jit.codeCache=.codecache
jit.threshold=0

and no files are generated when the program is run. Am I misunderstanding some aspect of how this feature works, or is this a feature that has since been removed?
