An unexpected error has been detected by Java Runtime Environment when working on Rad Image Viewer. This was first seen when trying to add 'brighten/darken' functionality to the viewer. RescaleOp seems to be the class to use (it's name I think is rather misleading). Unfortunately calling RescaleOp.filter() gives the JVM a heart attack.

This was with jdk 1.6 then I tried 1.5 and recieved the same result. Except that this time the problemetic frame for the crash is different libmlib_image.so+0x5c0d7. So I reckoned the problem would be with libmlib_image.so, whatever that is.

It turns out that the shared object in question is actually a part of the JVM rather than a system library (if you could call it that). So the conclusion is that this is definitely a bug in the JVM.
