Firefox and Sun Java

I installed the sun java package yesterday. Today I set up a link
ln -s /usr/java/latest/jre/lib/amd64/libnpjp2.so libnpjp2.so
in ~/.mozilla/plugins
to pull in the java plugin. After I restarted FF the plugin was not visible
and I got a SElinux alert
The firefox application attempted to make its stack executable. This is a
potential security problem.
This should never ever be necessary. Stack memory is not executable on most
OSes these days
and this will not change. Executable stack memory is one of the biggest
security problems. An
execstack error might in fact be most likely raised by malicious code.
Applications are sometimes
coded incorrectly and request this permission. The SELinux Memory Protection
Tests web page
explains how to remove this requirement. If firefox does not work and you
need it to work, you can
configure SELinux temporarily to allow this access until the application is
fixed. Please file a bug report.
Any ideas?
Paolo
