Keegan Witt closed GROOVY-7555.
-------------------------------
    Resolution: Invalid

This is a Groovy-Eclipse issue, not a Groovy issue.  Please open an [issue|https://github.com/groovy/groovy-eclipse/issues] with that project.  Be aware however, that we currently don't have a maintainer for that project so it might be a while before it gets resolved :(

>                 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}
> BUG! exception in phase 'canonicalization' in source unit 'C:\Users\erika01\git\component_tree_model\src\main\groovy\com\<company>\component\model\tree\template\Line.groovy' JDTClassNode.getTypeClass() cannot locate class for com.<company>.component.model.tree.template.ConfigurationObject using transform loader org.codehaus.jdt.groovy.internal.compiler.ast.GroovyParser$GrapeAwareGroovyClassLoader@6ee4820b
