Erika Redmark created GROOVY-7555:
-------------------------------------

             Summary: Even simple traits are not working at all when using Eclipse: Internal groovy compiler error
                 Key: GROOVY-7555
                 URL: https://issues.apache.org/jira/browse/GROOVY-7555
             Project: Groovy
          Issue Type: Bug
          Components: Compiler
    Affects Versions: 2.4.3
         Environment: Eclipse Luna, Windows 7 64bit, Groovy 2.4.3
            Reporter: Erika Redmark
            Priority: Critical


I have an extremely simple trait with literally nothing defined:

{code}trait ConfigurationObject { } {code}

And I implement it, once again no class body or methods defined in any way:

{code}class Line implements ConfigurationObject { }  {code}

And just like that, the Groovy compiler (2.4.3) on Eclipse Luna fails with an internal error:

{code}

I am using Eclipse Luna with the latest 2.4.3 Groovy compiler, and Java 8.
