The JRuby team released version 1.0.1 yesterday along with the plan for version 1.1, which is to be released before RubyConf in early November.

The 1.0.1 maintenance release:

• Resolves 28 issues
• Fixes multipart processing
• Fixes sockets that affected some of the net/* libraries
• Fixes network timeouts when using large packets

Per a message from Charles Nutter, the 1.1 plan includes:

• Compiler complete
• AOT compilation working with jrubyc
• stdlib all precompiled
• gem install precompilation
• virtual filesystem-inside-JVM (maybe) or hacked rubygems that can run out of an archive
• performance improvement to be quantified…java integration, execution, memory reduction
• yarv bytecode execution and compilation (maybe)
• AST sharing as an option (sharing across runtimes)…need to explore AOT compilation and its (positive?) effect on memory too
• real threading brutalization, testably multithread-safe core classes (maybe, needs heavy testing on many-core systems)
• Java API rubification, perhaps with require ‘javax.swing’ and so on

Grab the release and start deploying Rails apps in your Java environment.
