More fixes and a couple of optimizations. The bytecode optimizations and the removal of assert statements resulted in IKVM.OpenJDK.ClassLibrary.dll actually becoming smaller for once:
The size difference is about evenly split between the bytecode optimizations and the assert statement removal.
The ikvmc option to remove assert statements is a bit of a cheat, but it turns out that in at least one case (java.util.BitSet) the assertions significantly affect performance (even when they are disabled) on .NET. This is the result of the CLR JIT not optimizing them away whereas HotSpot completely removes them when assertions aren't enabled. Given that this was affecting a real world scenario for an ikvm user I decided to add this option and compile the core class library with it. The option will only remove assert statements that it recognizes (i.e. the example code pattern mentioned in appendix IV of the assert spec).

Remember Me
I apologize for the lameness of this, but the comment spam was driving me nuts. In order to be able to post a comment, you need to answer a simple question. Hopefully this question is easy enough not to annoy serious commenters, but hard enough to keep the spammers away.
Anti-Spam Question: What method on java.lang.System returns an object's original hashcode (i.e. the one that would be returned by java.lang.Object.hashCode() if it wasn't overridden)? (case is significant)
