What steps will reproduce the problem?
1. Use JavaIDE to compile project that has *.aidl files -- for example 
https://bitbucket.org/folone/repl-core/src/9834025ae2b2/src/com/folone/replcore/
REPL.java
2. The generation of the "stub" java files will fail

Please provide any additional information below.

The AIDL (Android Interface Description Language) is not well known or widely 
used but could become popular in the type of apps JavaIDE is good at compiling. 
 It is a 200k utility and could perhaps be ported the way aapt was.
