<Swing Dev> Regression test for 8016551 on Linux/Unix

[Volker Simonis]

Hi Leonid,

could you please explain, how the regression test you've added for
8016551 is supposed to work?

If I run this test standalone or within JTreg with '-othervm' option
on Linux the test displays a frame with the close icon and then it
throws an  sun.awt.SunToolkit$OperationTimedOut() exception because of
the call to SunToolkit.realSync():

Exception in thread "main" sun.awt.SunToolkit$OperationTimedOut: 10001
    at sun.awt.X11.XToolkit.syncNativeQueue(XToolkit.java:2427)
    at sun.awt.SunToolkit.realSync(SunToolkit.java:1501)
    at bug8016551.main(bug8016551.java:40)

Within JTreg, this of course makes the test fail. If running
standalone, the frame will be still displayed until I close the
window.

If I run the test within JTreg with the '-agentvm' option, it is even
not possible to call setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE) on
the created frame, because agent-VMs run with a SecurityManager which
forbids this (also see my mail to
http://mail.openjdk.java.net/pipermail/quality-discuss/2013-December/000175.html):

So I wonder how this test is supposed to work? Who will actually close
the created frame? Or is this supposed to be a manual test?

Thank you and best regards,
