Actually, jtreg is (has always been) optimised to *run* tests efficiently, with no time tax. 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.

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:

1. Options:  -noreport  (or -nr for short)
2. System property: javatest.noReportRequired

Jonathan: Here's a small jtreg feature request:
It's nice for release engineers to have jtreg check the whole test/ tree for correct test definitions. But for developers who are just doing

jtreg MyTest.java

they're not interested in awt failures, and don't want to pay the 10-second tax to check every test definition for every jtreg invocation.

    Martin,

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

    changeset:   16112:88faebbdbf9b
    user:        arapte
    date:        Fri Nov 04 21:55:19 2016 +0530
    summary:     8160766: [TEST_BUG] java/awt/Focus/DisposedWindow


    The problem edit looks like this:


     /*
    -  test
    -  @bug       6386592
    -  @summary   Tests that disposing a dialog doesn't activate its
    invisible owner.
    -  @author anton.tara...@sun.com <mailto:anton.tara...@sun.com>:
    area=awt.focus
    -  @run       applet DisposeDialogNotActivateOwnerTest.html
    +  @test
    +  @key headful
    +  @bug 6386592 8160766
    +  @summary Tests that disposing a dialog doesn't activate its
    invisible owner.
     */

    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.

    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.
