Description

Foo.groovy:

class Foo {
  static foo(String[] args) {}
}

Bar.java:

public class Bar {
  public static void main(String[] args) {
    Foo.foo("one", "two", "three");
  }
}

This compiles fine separately, but with joint compilation I get:

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
Compile error during compilation with javac.
Bar.java:3: foo(java.lang.String[]) in Foo cannot be applied to (java.lang.String,java.lang.String,java.lang.String)
		Foo.foo("a", "b", "c");
		       ^
1 error

I suppose stub generation is to blame.
