Description

Under JDK 1.4 rc2 I got following thread dump showing deadlock. The same code
works well under JDK 1.3.

Original: http://xml.netbeans.org/issues/show_bug.cgi?id=17992

This thread showed modal customizer dialog.

It sounds to be focus related when showing a dilaog from focusLost(). The dialog is not shown properly. (May be it want to call back another focus lost.) A simple case attached.

=============================================================

Here is the test case from the attachments.
I commented out the package statement.

CAP member had reported the same problem and this problem is serious enough
that they might have to move back to 1.3.1.

Their EventQueue got stuck, resulting in an application that wont redraw nor
respond to the user but that is otherwise alive. Attached their stack trace:

They have had this happen even when modal dialogs are not involved.
