    Latest Java release (1.6.0_25) crashes systematically on Firefox

      The online software developed by my company uses multiple Java applets on the page. When we tested the latest Java update (1.6.0_25) last week, we realized that Java would unexpectedly stop when used with Firefox.

      I managed to create a test page to reproduce this issue. In the page, I used applets available from java.com and javatester.org (it's simple applets which test your Java version).

      To reproduce it, go to [http://www.aleks.com/multi_applets_crash2|http://www.aleks.com/multi_applets_crash2] and click on refresh. After few times (usually less than 10 times) Java will stop and the applets won't be displayed. If you had the Java console opened at the same time, you would be able to see it close suddenly. No Java icon is visible in your Windows system tray.

      We tested with Windows XP, Vista and Windows 7 and with different versions of Firefox (4.01.1, 3.018, 3.5.10, 3.5.15, 3.6.3, 3.6.13 and 3.6.17). With Java 1.6.0_25, it always crashes.
      If you test with Java 1.6.0_24 it does NOT crash.
      If you test with other browsers (IE and Chrome) and Java 1.6.0_25, it almost never crashes.

      Any help would be greatly appreciated. If you think I should post this somewhere else, please advise (I will also post this issue on bugzilla.mozilla.org).
