I recently got some updates on my dapper ubuntu system (kernel 2.6.15-27-386, hal, lvm) and now I can't run intellij.  Here is the error I get.

$ /opt/idea-6107/bin/idea.sh

Has anyone seen this?  I initially thought it related to the new kernel, but when I rolled back it was still broken.  Most other java apps work fine although my build now fails when I try to generate code from xml with the following error. 

genAll:

java Generating 1 domain objects to /home/pair/trunk/devel/srcGenerated/com/foobaz/ae/insurance

java log4j:ERROR Parsing error on line 1 and column 2

java log4j:ERROR An invalid XML character (Unicode: 0x0) was found in the prolog of the document.

java log4j:ERROR Could not parse input source org.xml.sax.InputSource@10babaf.

I have posted in the ubuntu forums as well as here.  http://www.ubuntuforums.org/showthread.php?t=319305  Hoping for some help soon.  Thanks alot!
