    Actually, jtreg is (has always been) optimised to *run* tests
    efficiently, with no time tax.<br>
    But yes, there is a time tax, which comes from writing the report at
    the end of the test run, and that is actually where the clash is
    (probably) being detected.<br>
    <br>
    And, my guess is that a developer running "jtreg MyTest.java"
    doesn't need/want/care about the report. If so, there are two ways
    to disable the report:<br>
    <br>
    1. Options:  -noreport  (or -nr for short)<br>
    2. System property: javatest.noReportRequired<br>

            It looks like this is a test bug, introduced in this

             */<br>
            <br>
            Note that plain "test" was edited to "@test", meaning that
            the file previously was not a standalone jtreg test, and it
            was changed to be one.  This causes a clash with an HTML
            test of the same base name.<br>
            <br>
            jtreg correctly reports the clash, because both tests would
            lead to the same .jtr file.  i.e. you can't have two tests
            that only differ in their filename extension.<br>
