[jira] [Created] (GROOVY-10124) Scope of class header (extends, implements and type parameters) should not include class being declared

Eric Milles created GROOVY-10124:
------------------------------------

             Summary: Scope of class header (extends, implements and type parameters) should not include class being declared
                 Key: GROOVY-10124
                 URL: https://issues.apache.org/jira/browse/GROOVY-10124
             Project: Groovy
          Issue Type: Bug
            Reporter: Eric Milles


Similar to GROOVY-8063, the scope of the extends/implements clause is not consistent with Java.  Consider the following:
{code:groovy}
class C extends D {
  class D {
  }
}
{code}

Java compilers give an error like "D cannot be resolved to a type".  Groovy compiler resolves this without a qualifier.  This is a problem for Java integration (stubs, IDE, etc.) when the pre-resolved class (compile phase CONVERSION) is used.  This class compiles fine for Groovy but fails on the Java side either by not being able to resolve D or giving a cyclic reference error which groovy misses.
