Hi, Joe.

I would like to clarify the meaning of the headful tag. If the test complete successfully when the jtreg option contains:
    "-Djava.awt.headless=true -k:’headful’
or if DISPLAY variable contain some incorrect value, then this will mean that headful tag is not necessary in the test?

I think that headful tag is unnecessary in some tests, because these tests are passed in headless mode.
