The fix itself looks good but the test needs work.
It needs the GPLv2 - like all the other tests, and is missing the jtreg tags which allow the test harness to identify it as a test. and a few orher tags. Again take a look at other tests. Note that since you don't create any windows you will NOT need the @headful tag.

No point in HTML here ... nothing runs on this javadoc.
