Firefox may hang immediately. If it didn't hang, click the Reload button a few times. In my browser this always causes it to hang. The code above refers to a non-existant applet. Apparently that is what causes Firefox to hang. I distilled this code after trying to browse a half-broken site where some applets were missing. Reproducible: Always Steps to Reproduce: 1.Create a file with the given code. 2.Open that file. 3.If Firefox didn't hang, hit the Reload button a few times. Actual Results: Firefox hangs.

Created attachment 218556 [details] Testcase Testcase WFM using Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a1) Gecko/20060413 Firefox/3.0a1 ID:2006041304 Is this a problem in 220.127.116.11 only?

Summary: Very simple page that hangs Firefox → Hang on page with non-existent Java applet
Version: unspecified → 1.8 Branch
I tried the attachment from Comment #1, and it didn't hang my Firefox 18.104.22.168, even after several reloads. However, when opening a file stored in my computer, exactly with the same contents, it did hang after two reloads. One difference that I noticed was that, when opening the attachment from #1, it showed the animated "Java - Sun Microsystems" logo before writing, in the status line, "Applet testapplet notinited". However, when opening from the local file, it didn't show the animated logo.
Reporducible on Solaris platform Firefoxo 22.214.171.124, Jdk1.6.0.
I can reliably reproduce this hang * by hitting any-page-with-a-missing-applet * using Minefield 20061006; JVM & Plug-in 1.6.0-beta2; Windows XPSP2 on AMD64-Dualcore. UA=Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.9a1) Gecko/20061006 Minefield/3.0a1 PLUGIN=Java Plug-in 1.6.0-beta2 JVM=Using JRE version 1.6.0-beta2 Java HotSpot(TM) Client VM OS=XPSP2 (with weekly patches). HW=AMD Athlon(tm) 64 X2 Dual Core Processor 3800+ 2.01 GHz, 2.00 GB of RAM Physical Address Extension I suspect this is race condition at applet initialization time, which is exacerbated by an underutilized multi-processor... in effect a threading issue in the beta 1.6 JVM &/or Applet-plugin. see my related sun forum post: http://forum.java.sun.com/thread.jspa?messageID=4411650� see my comments on the open sun bug report: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6396012 see the ?related? closed sun bug report: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=6348224 I would very much like Sun to fix this bug... or FF to work around it.
