New Hybrid Snapshot

Major code bloat. I've now integrated the bulk of the OpenJDK code that isn't awt or swing. As a result the IKVM.Hybrid.GNU.Classpath.OpenJDK.dll assembly size has grown to about 26 MB. API coverage compared with JDK 1.6 is now at more than 98%. Note that doesn't mean that everything will work, because some back-end implementations are stubbed out or not included.

Disclaimers apply. I haven't done a full test pass on this build.

Changes:

  • OpenJDK: Integrated javax.management package (and sub packages).
  • OpenJDK: Integrated java.lang.management package (only a stub back-end implementation though).
  • OpenJDK: Integrated javax.imageio package (excluding the jpeg support, because OpenJDK uses native code for that).
  • OpenJDK: Integrated javax.activation, javax.annotation, javax.jws, javax.lang.model, javax.tools, javax.xml.*, org.jcp.xml.dsig.internal, org.relaxng.datatype, org.w3c.dom.*, org.xml.sax.* packages.
  • OpenJDK: Integrated javax.sql.* packages.
  • OpenJDK: Integrated javax.accessibility, javax.transaction, javax.activity packages.
  • OpenJDK: Integrated javax.print.* packages (no back-end implementation and ServiceUI is stubbed.)
  • OpenJDK: Integrated org.omg.*, javax.rmi.*, javax.sound.*, org.ietfs.jgss packages.
  • Fixed JNI NewObject method to actually create an object of the requested class, instead of the class of the constructor.
  • Added method name clash handling for AOT access stub methods.

Binaries available here: ikvmbin-hybrid-0.35.2769.zip.

Would you support AWT / Swing as the Sun Version?

Okay, just wanted to clarify what you mean by 'integrating'. My understanding is you actually replace the GNU Classpath code with code copied from OpenJDK and then try and implement the necessary VM wotsits -- is that correct? If that is the case, presumably the end goal is to complete replace all the Classpath code. At the moment, that'd be a real shame because it would make IKVM more broken as lots of stuff like AWT/Swing is broken on OpenJDK.

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)
