Description

[Himanshu]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1.1) Gecko/20090715 Firefox/3.5.1
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9.1.1) Gecko/20090715 Firefox/3.5.1

This may be a bug in the Java Embedded Plugin but noting it here as well: https://sourceforge.net/support/tracker.php?aid=2832144

Unable to log bug with Apple since their site is down.

Platform: Mac OS X 10.4 (Power PC), 10.5 (Intel Core 2 Duo)
Firefox: 3.5

Reproducible: Always

Steps to Reproduce:
1. Try to show a panel in the applet with a label which contains ImageIcon. Load the ImageIcon from the network.
2. Or try loading a ResourceBundle. The ResourceBundle should be bundled with the applet.


Since this is an issue with threads, you will notice errors occassionally.
Actual Results:  
Applet does not show up and firefox hangs

Expected Results:  
Applet should load properly without causing firefox to hang.

I've just released a new version of the Java Embedding Plugin
(0.9.7.3) that fixes this bug (by working around it).  For more
information see bug 551327.

JEP 0.9.7.3 has now landed on the 1.9.2 and 1.9.1 branches, and should
be in tomorrow's Firefox 3.6.3pre and 3.1.10pre nightlies (at
ftp://ftp.mozilla.org/pub/mozilla.org/firefox/nightly/).
