Description

When groovy class implements java interface located in other package with method returning array of java objects (not primitive), joint compilation fails with org.codehaus.groovy.control.MultipleCompilationErrorsException

Running joint compiler again compiles this groovy class successfully.

Attached file contains example files and script to run groovyc in joint compiler mode.
Run ./joint-compile.sh - MultipleCompilationErrorsException
Run it again - success.

To reproduce please remove created *.class files
Reproduced - always.

Workaround: add package name of returned java class to groovy method

    public foo.JavaDataObject[] ...
