The JRuby community is pleased to announce the release of JRuby 9.0.0.0.rc2

JRuby 9000 is the new version of JRuby, representing years of effort and
large-scale reboots of several JRuby subsystems. It is expected to be
compatible with Ruby 2.2.x and stay in sync with C Ruby.
Major features of JRuby 9000:
- Ruby 2.2 compatibility
- A new optimizing runtime based on a traditional compiler design
- New POSIX-friendly IO and Process
- Fully ported encoding/transcoding logic from MRI
We are hoping this is our last release candidate before JRuby 9.0.0.0. The
severity of problems are getting small enough where we think the next
release will be 9.0.0.0.
If you do find issues then report them on using 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.
It is important to point out that when we do put out JRuby 9.0.0.0 that
this is only the starting point. Our new internals gives us lots of
potential to keep pushing the bar higher on JRuby performance.
Notable updates since rc1
- Fixed cases where AOT classes were not loading
- Various performance fixes
- Reduced memory size
- More parser fixes
- Fixed rc1 eval with binding regression (aka setValueDepthZero AIOOB)
- 39 issues fixed for 9.0.0.0.rc2
Truffle
JRuby 9000 includes an preliminary 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 almost all Ruby language
features and the majority of the core library, and is able to run simple
gems and web frameworks such as Sinatra. It has no support for RubyGems,
Rails or any database drivers, 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.
