That's all I can think of. Some possibilities: Sun made a tweak to the math handling perhaps? ECJ no longer uses StrictMath (it's just too slow) though we could put it all in again. :-) I know there were changes to the hash table lookups but that's just speed, not behavior. Sorry Zheng, I'm not sure what Sun did. Sean On Jun 27, 2011, at 12:33 PM, J.
