[rules-users] 4.0 JBoss Rules IDE - JDK 1.4 compiler setting

[Mark Proctor]

We generate functions as static methods on a class, and then import 
those as static imports. Janino supports static imports and Eclipse can 
support static imports while still having jdk1.4 bytecode compatability 
- so we take advantage of that. Our next release will also be jdk1.5 only.
