class com.hp.ilo2.remcons.remcons.class not found

Working on an HP system I administrate I ran into the following java error message when trying to pull up the remote console in firefox on my linux workstation

• class com.hp.ilo2.remcons.remcons.class not found

What ended up being the solution was removing a cache directory that firefox has (clearing the cache from firefox did not work ...):

• Close All Firefox Windows
  
• cd $HOME/.mozilla/firefox/*.default/
• rm -rf Cache

Now start firefox back up and try it again, should be working (or at least it did for me).
