Major Description
Compiling a simple servlet against the Java EE 6 reference APIs results in a groovyc compilation failure. I have attached a project with both a Java Servlet and a Groovy Servlet.
The Java compiler works ok but the groovyc fails. Using Maven's eclipse-groovy-plugin also works ok. It seems that the groovyc compiler is introspecting the class in a different way than the maven eclipse-groovy-compiler.
