[Bug 383067] [NEW] Firefox hangs when using hava applet JSObject.getWindow()

[Kees]

Public bug reported:

Binary package hint: firefox-3.0

Firefox hangs (and uses 100% cpu) when java applets use
JSObject.getWindow() in combination with XMLlHttpRequests().

If I leave out the new XMLHttpRequest(), it does not happen.

Attached are: HelloWorld.java (13 lines) with the applet code and HelloWorld.class.
Also attached are index.html (38 lines), and gdb.txt with the stack trace of gdb of the running firefox process.

To reproduce: put HelloWorld.class and index.html in a subdirectory of
the webserver root directory, e.g. http://localhost/ffbug/.

I've experienced this first in Jaunty. Have tried an Intrepid fresh
install, but it didn't happen there, but after updating Intrepid with
the update-manager, the problem also appears.

This code is part of a larger application that ran fine under Ubuntu
Hardy. I switched to Jaunty mid May this year.
