82176 - NetGenesis applet causes browser to lock up, become unworkable [REQUESTOR: NetGenesis]

Status: RESOLVED INVALID

(Core Graveyard :: Java: OJI, defect, P1)

Description

[drapeau]

Net Genesis has an applet that, when run in the Netscape 6 or Mozilla browsers,
causes the browser's UI to become unresponsive.

There is currently no external test case for this applet yet; the URL listed in
this bug is Sun-internal, and is available only to Sun employees for now.

This applet also fails on Solaris, but for a different reason: the applet
hard-codes the usage of the "Arial" font, which is available on Windows but not
on Solaris.  The applet doesn't gracefull handle the error.  In any case, that
is a different problem (not an OJI bug), and I mention it here to point out that
this bug is specifically filed against Windows.

Marking as one of the OJI group's hot bugs.

Visiting the applet doesn't cause the browser hang.  Leaving the page causes 
this exception:


java.lang.IllegalStateException: Can't dispose InputContext while it's active

	at sun.awt.im.InputContext.dispose(Unknown Source)

	at java.awt.Window$1$DisposeAction.run(Unknown Source)

	at java.awt.Window.dispose(Unknown Source)

	at sun.plugin.navig.win32.PluginFrame.windowClosing
(PluginFrame.java:121)

	at java.awt.Window.processWindowEvent(Unknown Source)

	at java.awt.EventDispatchThread.pumpEventsForHierarchy(Unknown Source)

	at java.awt.EventDispatchThread.pumpEvents(Unknown Source)

Which causes the browser to hang.

Adding status to indicate actively being worked on by Ed right now.

Asked for insight from Stanley.

After determining that this bug is in the Java side, I've opened bugtraq bug 
4464761.  Re-assigning to Jim Melvin.

Removing status keyword since the bug is not an OJI escalation anymore (it's in
Java Plug-In).

Comment 8

I believe the bug is on the Java side because it appears that some necessary 
mechanism for removing the java implemented PluginFrame from its InputContext 
doesn't appear to be happening.  The exception happens because the 
InputContext's currentClient component is not null:

    public void dispose() {
        if (currentClientComponent != null) {
            throw new IllegalStateException("Can't dispose InputContext while 
it's active");
        }

[e-mail] closed the bugtraq bug 4464761 as not-reproducible with 
1.4.

The hang sounds like 4411534, which I could not reproduce in 1.4.

Talked to [e-mail] (the responsible engineer).  He can't reproduce 
this with 1.4 either.  

I'll close this as not reproducible.  If the bug is escalated, someone 
can reopen this report.
