Description

This compiles with javac but not with groovyc:

A.java

class A<TypeA extends A<TypeA, TypeB>,
        TypeB extends B<TypeB, TypeA>> {
}

B.java

class B<TypeB extends B<TypeB, TypeA>,
        TypeA extends A<TypeA, TypeB>> {
}

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
A.java: 1: unable to resolve class TypeB 
 @ line 1, column 32.
   class A<TypeA extends A<TypeA, TypeB>,
                                  ^

B.java: 1: unable to resolve class TypeA

   class B<TypeB extends B<TypeB, TypeA>,
                                  ^
