[ANN] JRuby 9.0.0.0.pre2 Released!

Thomas E Enebo
The JRuby community is pleased to announce the release of JRuby 9.0.0.0-pre2

    Homepage: http://www.jruby.org/
    Download: http://www.jruby.org/download

JRuby 9000 is the new version of JRuby, representing years of effort and large-scale reboots of several JRuby subsystems.

Major features of JRuby 9000:

    Ruby 2.2 compatibility, minus features listed below
    A new optimizing runtime based on a traditional compiler design
    New POSIX-friendly IO and Process
    Fully ported encoding/transcoding logic from MRI

This is our second preview release, and we are getting much closer to reaching our first .0 release. We are releasing this update to get user feedback on Ruby 2.2 functionality and overall stability.

We hope all Ruby users will try out this release and report issues on our issue tracker at http://bugs.jruby.org. We also encourage users to join our IRC channel (#jruby on Freenode) and mailing lists. You may also follow @jruby on Twitter for updates.

Ruby 2.2 features yet to be implemented:

  -  Refinements (partially finished) #1062
  -  Kernel#spawn close-on-exec support
  -  ObjectSpace::WeakMap#each and Enumerable inclusion
  -  Thread#handle_interrupt is not yet fully functional

Notable changes since pre1:

   - Startup time has improved but is a tiny bit slower than 1.7.x.
   - Memory usage has improved but still a ways to go.
   - Straight-line performance has improved since pre1
   - Windows support improved, but still needs further work and testing
   - Many keyword arguments problems fixed
   - 88 issues fixed for 9.0.0.0.pre2

The new runtime gathers more information about Ruby code and performs more analysis and optimization than our old runtime. There’s great potential here to bring Ruby performance to native Java or C, but we are just starting the optimization phase of that work. We will do our best to get startup time, memory use, and performance on par with 1.7.x (or better) before the final release of JRuby 9000.
Truffle

JRuby 9000 includes an in-development version of support for the Truffle language implementation framework and Graal VM from Oracle Labs. In future releases, Truffle will provide an extremely high performance and compatible backend for JRuby. The Truffle backend supports all Ruby language features, but so far only some of the core and standard libraries. It has no support for RubyGems or Rails, does not work on Windows, and is not ready to be tested with applications at this stage. More information on Truffle and Graal can be found in the JRuby Wiki.

Michael Pitman-2
Hi Tom,

That's all working much better on our machines now. We can now run
rails migrations and spec without any errors, which is fantastic.

An issue we are having, though, is when compiling some of our code
using jrubyc (using "jrubyc --verbose lib" to compile the lib
directory). The specific error is:

TypeError: failed to coerce org.objectweb.asm.ClassWriter to
org.jruby.org.objectweb.asm.ClassVisitor
  block in compile_files_with_options at
uri:classloader:/META-INF/jruby.home/lib/ruby/stdlib/jruby/compiler.rb:179
                                 call at org/jruby/RubyProc.java:303
  block in compile_files_with_options at
uri:classloader:/META-INF/jruby.home/lib/ruby/stdlib/jruby/compiler.rb:243
                                 each at org/jruby/RubyArray.java:1571
  block in compile_files_with_options at
uri:classloader:/META-INF/jruby.home/lib/ruby/stdlib/jruby/compiler.rb:242
                                 each at org/jruby/RubyArray.java:1571
           compile_files_with_options at
uri:classloader:/META-INF/jruby.home/lib/ruby/stdlib/jruby/compiler.rb:233
                         compile_argv at
uri:classloader:/META-INF/jruby.home/lib/ruby/stdlib/jruby/compiler.rb:94
                                <top> at ./jrubyc.rb:3


Does anyone have any ideas about what the problem could be here, or
any way I can help better identify the root cause?

Thanks,

Michael

Re: [ANN] JRuby 9.0.0.0.pre2 Released!

Thomas E Enebo
Oh...Can you file a bug for this?  We thought we nailed this one but Java limits method bodies to 32k and our AOT subsystem is generating a method larger than that. We just need to make sure we break things up into smaller pieces....but it is a little weird since our new system is much better at coping with this than JRuby 1.7.x.

We will be sure to get this settled for 9krc1.
