Bugzilla Bug 30577

JRE/JDK ebuilds currently install their own symlinks in
/usr/lib/nsbrowser/plugins.  Installing ibm-jdk after blackdown-jdk results in
two Java browser plugins, javaplugin_oji.so and libjavaplugin_oji.so.  IBM's
libjavaplugin_oji.so doesn't initialize, presumably because the environment is
still set for Blackdown.  (Even if it did work, running two Java plugins
simultaneously is of dubious value.)  IMO, java-config --set-system-vm should
control which browser plugin is used, not the ebuilds.  There is already
(undocumented) code in java-config for displaying plugin info; perhaps that
could be expanded to also control the plugins.

Reproducible: Always
Steps to Reproduce:
1. install blackdown-jdk
2. install ibm-jdk
3. run "mozilla about:plugins"

Actual Results:  
% mozilla about:plugins
LoadPlugin: failed to initialize shared library
/usr/opt/ibm-jdk-1.4.1/jre/bin/libjavaplugin_oji.so
[/usr/opt/ibm-jdk-1.4.1/jre/bin/libjavaplugin_oji.so: undefined symbol:

Expected Results:  
It shouldn't have installed the symlink in /usr/lib/nsbrowser/plugins in the
first place.
