The package RH releases puts it under
/usr/lib/jvm/java-1.6.0-sun-1.6.0.26.x86_64/jre/, so my link is
/usr/lib64/mozilla/plugins/libnpjp2.so ->
/usr/lib/jvm/java-1.6.0-sun-1.6.0.26.x86_64/jre/lib/amd64/libnpjp2.so

file tells me it is 64 bit. ldd looks good.

Interesting: I was firing it up again, and was about to strace it, when it
immediately crashed, trying to restore the last link I clicked on, to "is
java enabled", with
 Exception in thread "main" java.lang.NoClassDefFoundError:
sun/plugin2/main/server/MozillaPlugin
Caused by: java.lang.ClassNotFoundException:

firefox:
../../../../src/plugin/share/plugin2/npjp2/MozPluginInstance.cpp:241: bool
MozPluginInstance::SetWindow(void*, unsigned int, unsigned int, unsigned
int, unsigned int, unsigned int, unsigned int, unsigned int, unsigned
int): Assertion `m_pluginObject != __null' failed.

I just rm'd the link to /usr/lib64/mozilla/plugins-wrapped/libnpjp.so.1,
and it no longer crashes instantly on going to the javatester version
page.

Ok, now for the strace... nice, I click on the enabled link, and it
crashes with a SEGV.

More looking to do...
