New Development Snapshot

I've finally updated to a new drop of OpenJDK. If you want to build IKVM from source you'll need the directory resulting from a full build of OpenJDK 6 b10 on Linux AMD64 (although I suppose that if you change the paths in ikvm/openjdk/allsources.lst you'll be able to use an x86 version as well). At some point I'll release a zip file containing just the needed artifacts, but that will take some more time.

IKVM.OpenJDK.ClassLibrary.dll grew in size to 31,657,984 bytes, mostly because the character de-/encoders that live inside charsets.jar are now included as well. I know size is a big issue for many people and as previously discussed I'm still planning to split the class library assembly into several different files.

Changes since previous development snapshot:

  • Integrated OpenJDK 6 b10.
  • Fixed Method.getParameterAnnotations() bug introduced by CallerID support.
  • Changed forked AbstractQueuedSynchronizer to use AtomicReferenceFieldUpdater instead of map.xml based compareAndSet methods to reduce the number of differences between upstream and our version.
  • Fixed three String bugs found by OpenJDK string tests.

WARNING: THIS IS A DEVELOPMENT SNAPSHOT, NOT AN OFFICIAL RELEASE.

Development snapshots are intended for evaluating and keeping track of where the project is going, not for production usage. The binaries have not been extensively tested and are not strong named.

If you want to run this version on Mono, you'll need a Mono version built from recent svn, it does not work on Mono 1.9.

Binaries available here: ikvmbin-0.37.3086.zip

Any chance of updating to OpenJDK b28, a lot of functionality and bug fixing has been added since b10 :)

This is OpenJDK *6* b10, not OpenJDK 7.

Jeroen, Let me thank you again for the great tool you've created. At my company we are still amazed to see large part of our Java system successfully running on .NET platform thanks to IKVM.

We plan to use IKVM heavily in our technology stack. Our company develops a product for financial data integration and analytics. IKVM will be used to interface our Java-based server with C# based front end. IKVM allows to reuse Java code in .NET modules. For instance, the same ActiveMQ messaging code written on Java now also brings data to our C# application.

I just filed two bugs 2001799 and 2001802. Both contain fix recommendations. I've also submitted my Ant task for IKVMC to http://ant-ikvmc.sourceforge.net . Besides the task this small library also contains Java doclet to generate mapping file for a given set of Java classes.

I hope I can contribute more to IKVM as time goes.

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)
