When launching webex from firefox or chromium browser. Browser freezes and stops responding. Browser process must be killed to exit. Please help me troubleshoot this.

Here are my setup details and error messages I have gathered below:

Setup: Ubuntu 12.10 and all software updates installed. From Java Console: Java Plug-in 1.6.0_43 Using JRE version 1.7.0_17-b02 Java HotSpot(TM) Client VM

running file which java javac shows the following:

/usr/bin/java:  symbolic link to `/etc/alternatives/java'
/usr/bin/javac: symbolic link to `/etc/alternatives/javac'

I have several Java's loaded: running command sudo update-alternatives --config java produces:

There are 4 choices for the alternative java (providing /usr/bin/java).

  Selection    Path                                           Priority   Status

The Java console produces the following output when attempting to start webex:
