I got a little side tracked by the investigation of the Google Collections test suite performance issue, reported by Albert Strasheim in the comments to the previous snapshot.

This caused me to do some work on exception handling (unfortunately without any performance benefit to the Google Collections test suite) which, in turn, triggered something I've been wanting to do for while, namely to introduce a stub version of IKVM.OpenJDK.Core.dll which can be referenced by IKVM.Runtime.dll during FIRST_PASS compilation, to make it possible to have a cyclic dependency between IKVM.Runtime.dll and IKVM.OpenJDK.Core.dll for method signatures and not just the method bodies as was previously the case.

Changes:

• Added (limited) support to ikvmc for cyclic dependency compilation. The build now takes advantage of this to make it possible to use strongly typed method signatures for "native" methods implemented in IKVM.Runtime.dll.
• Changed reflection to convert any Method|FieldAccessExceptions to occur (in partial trust) into IllegalAccessException.
• Fixed type conversion verification issues in reflection dynamic methods.
• Moved exception handling code to IKVM.Runtime.dll (for IKVM.OpenJDK.Core.dll) and cleaned up several issues. Changed mapping API to be more efficient (in terms of bytecode size, and to allow stack trace collection to be bypassed for discarded remapped exceptions).
• Added new public API to unmap exception (ikvm.runtime.Util.unmapException()).
• Fixed loop counter integer overflow bug in tableswitch bytecode parsing. Bug #3009543.
• IKVM.Reflection: Fixed bug in constructor importing that could cause Module.ResolveMethod() on ModuleBuilder to return the underlying MethodInfo instead of the ConstructorInfo wrapper.
