[jruby-user] Minified JRuby

Anyone thought of making JRuby micro edition or something like that? On
my PC (yes, it is slow a bit) compiling Android project with JRuby and
MultiDex enabled takes about 6 hours. Yes, not kidding. For comparison,
compiling Android project with LuaJ takes approx 10-15 mins and with
Rhino about 10 mins on my PC. 13 MB of source code? That is really a
lot. I messed with JRuby-Core 1.7.20-SNAPSHOT source code and this is
result:

jRuby core 1.7.20-SNAPSHOT:
  - 7 + 1356 + 202 source files
  - 44 + 1 resources
  - 13 175 KB

jRuby codename micro:
  - 7 + 914 + 122 source files
  - 44 + 1 resources
  - 10 659 KB

  - changes:
    - removed JSR223, OSGI and BSF embedding
    - removed Psych (YAML) ruby library
    - removed Zlib ruby library
    - removed Nailgun support
    - removed Tempfile ruby library
    - removed NKF ruby library
    - removed BigDecimal ruby library
    - removed Digest ruby library
    - removed Etc ruby library
    - removed Fcntl ruby library
    - removed Iconv ruby library
    - removed IO ruby library
    - removed Mathn ruby library
    - removed Net ruby library
    - removed Pathname ruby library
    - removed Securerandom ruby library
    - removed Socket ruby library
    - removed Stringio ruby library
    - removed Strscan ruby library
    - removed Timeout ruby library
    - removed FFI ruby library
    - removed command-line interface
    - removed ant integration
    - removed IR
    - removed Ruby 1.9 and Ruby 1.8 support

  - todo:
    - remove ShellLauncher

But I am not sure if I do not actually bugged it. I tested it and it was
working fine and it reduced build time by more than one hour. So, I am
asking, anyone thought about following mruby pattern for some JRuby
micro edition?
