FULL PRODUCT VERSION : java version "1.7.0" Java(TM) SE Runtime Environment (build 1.7.0-b147) Java HotSpot(TM) Client VM (build 21.0-b17, mixed mode, sharing) ADDITIONAL OS VERSION INFORMATION : Microsoft Windows [Version 6.1.7601] (Windows 7 SP1, 64bit) EXTRA RELEVANT SYSTEM CONFIGURATION : 32-bit IE9 and 32-bit Java A DESCRIPTION OF THE PROBLEM : Loading a page with an applet will randomly fail to work. From the logfile it looks like the plugin part fails to communicate with the JVM (browser plugin crashed?). Firefox 4 and 5 did not have this problem on the same machine. Reverting to Java6 makes it work again in IE9. Also tested on Vista/IE8 and there it also works for me. Was repeatable on a second windows7/IE9 machine. REGRESSION. Last worked in version 6u26 STEPS TO FOLLOW TO REPRODUCE THE PROBLEM : Load/Reload the page a few times (5-10 times max). Enabling trace/logging seems to make it easier to trigger (looks like a race condition). EXPECTED VERSUS ACTUAL BEHAVIOR : EXPECTED - No crash. ACTUAL - Browser reports "A problem with this webpage caused Internet Explorer to close and reopen the tab" and reloads the page, or sometimes closes it. I did have a hs_err_pid*.log file but am unsure if that was from testing this. Removed it but were unable to generate a new one so probably not.

This whole thing could be an IE bug.
