Noticed coverage loss for javax.tools.ForwardingFileObject for some of its methods, please see attached screenshots

Found out that an explicit invocation of say method delete() which coverage is not recorded any more happens approximately the following way

    public void delete0001() {
        return new TestRunner(){
            protected void execute() { testedInstance.delete(); }
        }.executeTest();
    }

It's interesting that method FileObject::toUri() which is implemented by ForwardingFileObject and called by the tests the same way was not affected
