Reporter, Bugzilla is for Mozilla bugs only. Bugs in Netscape products (4.x and 6) must be 
reported via Netscape's own Bug Reporting Form ([http://help.netscape.com/forms/bug-
client.html]).

[Greg K.]

Reopening per reporter as MRJ Plug-In bugs are supposed to be reported in
Bugzilla whether Nav >=4.6 or Mozilla.

Added URL (had to create a publicly accessible page).

Can you attach the Crystal Reports Viewer to this bug or point us to a URL for it?

What  is the original filename of that ZIP; ReportViewer.jar?

Comment 8

Yup

David, I got that JAR installed and watched it load fine under Nav 4.7.8 and Moz 0.9.3. I 
wasn't sure how to load a report, though, so I just closed the windows in both browsers 
and didn't see any errors. How do I load a report?

(Also, just to be sure, did you install the "MRJPlugin (4.X)" into your Nav 4 plug-ins folder, 
or the "MRJPlugin" intended for NS 6/Moz?)

There's no problem with loading, the error is displayed when you close the
window.  It happens about 1/4 of the time, and it doesn't matter whether there's
a report loaded or not.  I suspect that it doesn't matter which applet is loaded
either.

Yes, I'm sure I'm using the correct Plug-in.

To reporoduce, create twenty or so netscape windows with the URL I've provided.
 Close them one at a time.  On some of them, you'll get a system modal dialog
that reports a java.lang.NullPointerException.

Okay, just tried that in Moz 0.9.3 and Moz crashed on the first window close request. 
(TalkBack ID TB34329054E.) Will try on Nav 4.7.8 next after I restart.

[Greg K.]

Just finished testing using Nav 4.7.8 and reproduced the problem David reports herein. I 
opened 20 windows with his URL and closed them one-by-one. Six of these close 
operations resulted in the Exception dialog he reports. Confirming.

Comment 13

[Greg K.]

Just tried retesting under Moz 0.9.3, this time with only five windows open to the URL. 
Moz again crashed the first time I tried to close a window (TB34329890X). Reporter, did 
you have any luck testing under Moz 0.9.3?

Comment 14

[David Himelright]

Just downloaded Moz 0.9.3 and reproduced the bug.  It took 8 tries this time,
and instead of a system modal dialog, I got a frozen Mac and what looked like
the system debugger or an empty system 7-style system modal dialog box.

This bug is targeted at a Mac classic platform/OS, which is no longer supported
by mozilla.org. Please re-target it to another platform/OS if this bug applies
there as well or resolve this bug.

I will resolve this bug as WONTFIX in four weeks if no action has been taken.

[Benjamin Smedberg]

Mass-closing bugs in the "OJI" component: OJI plugin integration was replaced with npruntime long ago, and these bugs appear to be irrelevant now. If there is in fact a real bug that remains, please file it new in the "Core" product, component "Plug-ins".
