------------------------------------

hi Charles,

The patch has already been submitted, the deed is done.

In our survey of the code, there were about 4 different libraries embedded and 
included in JRuby, some of LGPL some of GPLv3.

Some of them look pretty fundamental, such as the dependency on: 
http://code.google.com/p/jvm-language-runtime

As you probably know, the ASF has pretty strict rules regarding licensing, so 
undoing the downgrade is not possible until a JRuby that has ASF compatible 
licensing is available. 

> Our jruby jar has *GPL jars in it; fix

> The latest JRuby's complete jar bundles *GPL jars (JNA and JFFI among 
> others).   It looks like the functionality we depend on -- the shell in 
> particular -- makes use of these dirty jars so they are hard to strip.  They 
> came in because we (I!) just updated our JRuby w/o checking in on what 
> updates contained.  JRuby has been doing this for a while now (1.1.x added 
> the first LGPL).  You have to go all the ways back to the original HBase 
> checkin, HBASE-487, of JRuby -- 1.0.3 -- to get a JRuby w/o *GPL jars.
> Plan is to try and revert our JRuby all the ways down to 1.0.3 before 
> shipping 0.90.0.  Thats what this issue is about.
> We should also look into moving off JRuby in the medium to long-term.  Its 
> kinda awkward sticking on an old version that is no longer supported.  I'll 
> open an issue for that.
