// Note there is no @ in front of test above. This is so that the
// harness will not mistake this file as a test file. It should
// only see the html file as a test file. (the harness runs all
// valid test files, so it would run this test twice if this file
// were valid as well as the html file.)
// Also, note the area= after Your Name in the author tag. Here, you
// should put which functional area the test falls in. See the
// AWT-core home page -> test areas and/or -> AWT team for a list of
// areas.
// Note also the 'ConstructorsNullTest.html' in the run tag. This should
// be changed to the name of the test.
