What No Comments?

Thanks to everybody who commented on the JamVM 2.0.0 release, and apologies it's taken so long to approve them - I was expecting to get an email when I had an unmoderated comment but I haven't received any.

To answer the query regarding Nashorn.  Yes, JamVM 2.0.0 can run Nashorn.  It was one of the things I tested the JSR 292 implementation against.  However, I can't say I ran any particularly large scripts with it (it's not something I have a lot of experience with).  I'd be pleased to hear any experiences (good or bad) you have.

So now 2.0.0 is out of the way I hope to do much more frequent releases.  I've just started to look at OpenJDK 9.  I was slightly dismayed to discover it wouldn't even start up (java -version), but it turned out to be not a lot of work to fix (2 evenings).  Next is the jtreg tests...

JamVM 2.0.0 Released

I'm pleased to announce a new release of JamVM.  JamVM 2.0.0 is the first release of JamVM with support for OpenJDK (in addition to GNU Classpath). Although IcedTea already includes JamVM with OpenJDK support, this has been based on periodic snapshots of the development tree.

JamVM 2.0.0 supports OpenJDK 6, 7 and 8 (the latest). With OpenJDK 7 and 8 this includes full support for JSR 292 (invokedynamic). JamVM 2.0.0 with OpenJDK 8 also includes full support for Lambda expressions (JSR 335), type annotations (JSR 308) and method parameter reflection.

In addition to OpenJDK support, JamVM 2.0.0 also includes many bug-fixes, performance improvements and improved compatibility (from running the OpenJDK jtreg tests).

The full release notes can be found here (changes are categorised into those affecting OpenJDK, GNU Classpath and both), and the release package can be downloaded from the file area.
