Description

I tried to see if this was already fixed or covered by another issue, but I couldn't find something like it... Here is the code:

class Foo {
    @groovy.transform.CompileStatic
    public void blah() {
        ((GroovyObject)this);
    }
}

This is currently causing me an issue when trying to build grails-core in STS (it has a snippet somewhat similar to this, but obviously it does a bit more). For some reason it works through the gradle build on the command line, but not if I just run groovy 2.0.0 groovyc against that class above. I also grabbed a snapshot and tried it, which seemed to give the same result.

Oh, the error is:

> groovyc Foo.groovy
org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
Foo.groovy: 4: [Static type checking] - Inconvertible types: cannot cast Foo to groovy.lang.GroovyObject
 @ line 4, column 3.
   		((GroovyObject)this);
     ^
