This one seems like a straightforward bugfix to me, with some cleanup attached. And I've prepared some more cleanup in that area already which is dependent on this fix - so I'd appreciate if this wouldn't be procrastinated too much :)
I went through the change and they look okay to me (much smaller than I 
was expecting). I think we will need to figure out a solution for the 
JPLIS agent at some point because it shouldn't be using functions in 
libjava (having the VM use the function isn't too bad I suppose).
