Jeff,

that's a good question, our jj2000 jar is included in our packages. Like you 
said jj2002 is being referenced, not our jj2000. Our jj2000 package doesn't 
reference any other "external" packages. On the mac, it seems that the jj2000 
package references the jj2002 package. so my guess is that the way the build is 
set up that the JVM jj2000 package is being used before the our package jj2000.
