Are both plugins symlinked into Firefox plugin directory or is the icetea installer is removing the sun symlink ?
Do you see both plugins under about:plugins ?

You can't choose which plugin do you want to use, that's a different bug but you should see both plugins in the addon manager/Plugins and disable one if you want to use the other one.

there was only one plugin in about:plugins. i don't think that icedtea is removing anything, as i first installed icedtea, then sun plugin, and sun plugin was not visible.

Can you look in the plugin folder ?
Are there 2 symlinks for both plugins or only one ?

OK, I installed icedtea6-plugin, sun-java disappeared from about:plugins and in /usr/lib/plugins there is no java at all

pawel@lambda:~$ ls -l /usr/lib/firefox/plugins/
razem 0
lrwxrwxrwx 1 root root 37 2010-07-06 18:09 flashplugin-alternative.so -> /etc/alternatives/firefox-flashplugin
pawel@lambda:~$

then I did apt-get purge icedtea6-plugin, refreshed about:plugins, and there is again sun java and no icedtea.

when You want me to look for plugins in diffrent directories name them. but i'm pretty sure that you should be abble to recreate this bug on your own ubuntu 10.04 64bit.

I'm a win32 user but have you looked under /usr/lib/mozilla/plugins ?

OK, i looked deeper, and now i know where is problem. it's in ubuntu's (debian?) 'alternatives' mechanism.

in /usr/lib/mozilla/plugins is libjavaplugin.so , which links to /etc/alternatives/mozilla-javaplugin.so .

pawel@lambda:~$ ls -l /usr/lib/mozilla/plugins/

to change which plugin should be used by firefox one have to use 'update-alternative' commnad. 

pawel@lambda:~$ update-alternatives --list mozilla-javaplugin.so
/usr/lib/jvm/java-6-openjdk/jre/lib/amd64/IcedTeaPlugin.so
/usr/lib/jvm/java-6-sun/jre/lib/amd64/libnpjp2.so
pawel@lambda:~$

usually, alternatives are updated by packet post-install scripts, i.e. when you have only openjdk installed command 'java' point to openjdk, and then when you install sun-java packet,  java is automaticly switched to sun's version. but it doesnt work wich java=plugin. when you install icedtead javaplugin point to icedtea, and after installing sun-java it still point to icedtea. i guess there is nothing youc can do about it, in mozilla, but i think you should describe it somewhere in FAQ , 'how to change java plugin in ubuntu? use update-alternatives --config mozilla-javaplugin.so'.

maybe you can talk with ubuntu about fixing it, it affects your product after all. in ubuntu the default java plugin is icedtea, as 'open implementation', but sun's plugin works better. and when users install sun's plugin firefox doen't notice it.

I'm just a user like you and you can eplain the issue better to them.
Please report that to ubuntu under https://bugs.launchpad.net/ubuntu but search for existing reports because it could be already reported.
