Issue with _JETGROOVY_EVAL_() in the debugger with grails.

When tyring to evaluate anything in the debugger in a grails app, the result of the evaluation is the following exception.

result = {org.codehaus.groovy.runtime.InvokerInvocationException@15328}Method threw 'org.codehaus.groovy.runtime.InvokerInvocationException' exception.
module = null
node = null
detailMessage = null
cause = {groovy.lang.MissingMethodException@15661}"groovy.lang.MissingMethodException: No signature of method: com.something.AppService._JETGROOVY_EVAL_() is applicable for argument types: () values: []"
stackTrace = {java.lang.StackTraceElement[164]@15330}

Googling only gives me a hit in org.jetbrains.plugins.groovy.debugger.GroovyCodeFragmentFactory!

I dont really have a specific question as I am not really excited to debug grails stuff one more time.

If you have something to say about that, you can say it here.

This is with grails 2.1.3 and intellij 13.0.1

I am pretty sure I saw this error also in intellij 12.
