Firefox Java plugin with 7.0?

I'm like to ask what people are using for Java plugin with Firefox. There were
a few recent threads on this subject but no definitive answer:

I tried compiling jdk15 port and was able to build it and install it
successfully. However, when trying to load a java applet in Firefox, the
browser seemingly crashes (exits). I then tried following the method described
in the handbook by downloading the diablo-jre-freebsd6.i386.1.5.0.07.01.tbz
package from FreeBSD Foundation website and adding it with pkg_add. Trying to
load java applets crashes Firefox. In both cases, javavmwrapper was installed
and about:plugins in Firefox shows that java plugin is installed. Is there a
working combination for 7.0-PRERELEASE/BETA?

My system is:

# uname -a

Currently with jre from FreeBSD foundation site:
# pkg_info | grep jre
diablo-jre-1.5.0.07.01 Java Runtime Environment 1.5.0_07.01
