[rules-dev] ClassFieldInspector and Groovy Classes

The attached diff (against 3.0.5 sources) adds a condition to the ClassFieldInspector to not analyze methods named <clinit>. For some reason, the Groovy compiler is outputing classes that were causing this check to choke and throw an IllegalArgumentException because of a <clinit> method with ACC_PUBLIC access code. Applying this patch allows Drools to operate correctly with compiled Groovy Fact classes. This seems like a pretty innocuous change that someone should apply to SVN. Unfortunately, it is rather difficult to create a test case for it. Terry Laurenzo
