problem with XFCE panel and java plugin

[Glenn Johnson]

I have a rather strange problem on my system.  My system is FreeBSD-4.7
with XFCE 3.8.16.

I have a launch button for mozilla.  When I use that button to launch
mozilla all is well until I go to a site with java.  Then the browser
crashes.  This problem does not show up if I launch from a terminal
window or if I launch from xfrun.  This problem does not show up if I
launch from the gnome panel, only the xfce panel.

I enabled the "Show subprocess diagnostic dialog" and here is the output
I am getting when I try to go to a page with java:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Internal error : Could not dup 43 into 11
INTERNAL ERROR on Browser End: Could not read ack from browser
System error?:: Resource temporarily unavailable
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

This also generates a plugin131.trace file, with the following contents:

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

As I said, the mozilla java plugin works fine if I launch mozilla from
any means other than the XFCE panel.

Thanks.
