Bug Description:





Steps to Reproduce (be specific):


    1. Download FFJ Community Edition from:
http://edist.central/edist-cgi/showtool.cgi?tool=Forte+for+Java&version=2.0
(Download the file: forte_ce_2.class)

    2. Install it
     /usr/j2se/bin/java forte_ce_2
<InstallShield starts... do the obvious>

    3. Assuming you have a jdk 1.3 available at /usr/j2se, you should be able
     to just start it up with no errors:
     ./forte4j/bin/runide.sh
    
    4. Run it with 1.4 b46 as follows:
        ./forte4j/bin/runide.sh -jdkhome /export/home2/jdk1.4.0
    
     And you get a raft of exceptions, look at file:
     ./forte4j/system/ide.log
