This one's pretty important to me:

  http://jira.codehaus.org/browse/JRUBY-2495
  Requiring and using a Java library that ends up using a Thread Context classloader doesn't work.

Here's the problem in a nutshell:

I get classnotfound errors when I try and use a Java library from a JRuby program when the library tries to dynamically create classes that are only defined by class resources accessible to the JRuby class loader (example: XMLDecoder).

The issue is caused because the libraries use a thread context classloader which in the current implementation is only available to the ancestors of the JRuby class loader.

Lots more detail in the Jira report.
