JDK-Info:
---------
java version "1.6.0-ea"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.6.0-ea-b46)
Java HotSpot(TM) Client VM (build 1.6.0-ea-b46, mixed mode)


System-Info:
------------
Solaris


Steps to Reproduce:
-------------------
1) Install JDK 6.0 b45
2) Install mozilla 1.7
3) Create the link for libjavaplugin_oji.so file under <mozilla>/plugins pointing to $jdk1.6.0/jre1.6.0/plugin/sparc/ns7/libjavaplugin_oji.so

(ln -s /tmp/ramkumar/b45/jre1.6.0/plugin/sparc/ns7/libjavaplugin_oji.so libjavaplugin_oji.so under <mozilla>/plugins) So, now the browser jre is pointing to b45

4) Clean cache (\rm -rf ~/.java)
5) Launch an applet which fails to load (e.g. delete $jdk1.6.0/demo/applets/DrawTest/DrawControls.class and load $jdk1.6.0/demo/applets/DrawTest/example1.html applet)

6) When applet fails to load, right-mouse click on the failed applet box box and click "About Java(TM)" on the popup menu

The "About Java" dialog shows java version as "Version 1.6.0-ea (build 1.6.0-ea-b45)", which is expected.

7) Now Install JDK 6.0 b46
8) Exit browser and re-create link for libjavaplugin_oji.so file under <mozilla>/plugins pointing to b46 $jdk1.6.0/jre1.6.0/plugin/sparc/ns7/libjavaplugin_oji.so

(ln -s /tmp/ramkumar/b46/jre1.6.0/plugin/sparc/ns7/libjavaplugin_oji.so libjavaplugin_oji.so under <mozilla>/plugins) So, now the browser jre is pointing to b46

9) Launch the same applet which fails to load [Donot clear java cache]
10) When applet fails to load, right-mouse click on the failed applet box box and click "About Java(TM)" on the popup menu

The "About Java" dialog still shows java version as "Version 1.6.0-ea (build 1.6.0-ea-b45)" which should be b46

Content of java console [browser jre is pointing to b46 after link to b45 is deleted and recreated, pointing to b46]:

java.class.path = /tmp/ramkumar/b45/jre1.6.0/classes
java.class.version = 49.0
java.class.version.applet = true
java.endorsed.dirs = /tmp/ramkumar/b45/jre1.6.0/lib/endorsed
java.ext.dirs = /tmp/ramkumar/b45/jre1.6.0/lib/ext
java.home = /tmp/ramkumar/b45/jre1.6.0
java.io.tmpdir = /var/tmp/
java.library.path = /tmp/ramkumar/b45/jre1.6.0/lib/sparc/client:/tmp/ramkumar/b45/jre1.6.0/lib/sparc:/test-browser/mozilla_1.7.5_sparc:..:../plugins:/usr/local/lib/mre/mre-1.7.5:/usr/lib
java.protocol.handler.pkgs = sun.plugin.net.protocol|com.sun.deploy.net.protocol
java.runtime.name = Java(TM) 2 Runtime Environment, Standard Edition
java.runtime.version = 1.6.0-ea-b45


Actual Behavior:
----------------
When browser jre is pointing to a different jre and java cache not cleared, browser is still showing/pointing to the old values (java.home, java.runtime.version)


Expected Behavior:
------------------
Browser jre should pick the jre, currently pointed at
