New Snapshot

The GNU Classpath 0.95 release branch has been created (0.94 was skipped), so it shouldn't be long now before I will release IKVM 0.34, but before that here's a final snapshot containing everything that will be in 0.34.


  • Integrated current GNU Classpath cvs version.
  • .NET "generic class loaders" now return something (mildly) sensible when toString() is called on them.
  • ikvmc no longer warns about generic stubs.
  • ikvmstub now has WHIDBEY conditional code to properly determine if a class is a generic type instance (instead of the name based hack).
  • Fixed .NET generic type name mangling bug (nested generic types were double encoded).
  • Added support for loading .NET generic type stubs.
  • Fixed several .NET generic type loading bugs.
  • Fixed ikvm.runtime.Util.getInstanceTypeFromClass() to return null instead of throw an exception when it is called on a "dynamic only" class.
  • Changed ikvmstub to use java.util.zip instead of SharpZipLib.
  • Fixed index/length overflow detection in arraycopy_primitive_n methods.
  • Fixed JNI init args and thread attach string conversions.
  • Added workaround for .NET bug that caused OverflowException when compiling a class with an initialized final instance field of type char with a value > 32K.

Binaries available here: ikvmbin-0.33.2655.zip

I'm new to IKVM.NET (this is the first snapshot I've tried). I'm following the instructions in another blog entry to setup IKVM as a JRE in Eclipse.

One of the steps is to run ikvmstub on some version of mscorlib.dll.

I'm running Windows XP SP2 (with all updates applied) on a 32-bit machine. ikvmstub works fine on C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322\mscorlib.dll
but when running it on C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\mscorlib.dll I get this error:

Unhandled Exception: System.BadImageFormatException: The format of the file 'mscorlib.dll' is invalid.

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)
