I checked out/built the JRuby workspace and installing Rails is
giving the following error:
C:\workspaces\jruby-trunk>bin\jruby -S gem install rails
–include-dependencies --no-ri --no-rdoc

I fixed it by specifying the switch “-J-Xmx384M”. So the command that
works is:
bin\jruby -J-Xmx512M -S gem install rails --include-dependencies --no-ri
–no-rdoc
