[xwiki-users] Error displaying history after upgrade to 1.2m1

I upgraded from version=1.1-rc-1.4635 to version=1.2-milestone-1.5235 I also moved from the default Jetty servlet container to Tomcat 6.0.14. I'm using the default HSQLDB setup and driver. After copying the database files to the new location and tweaking the nessisary files in WEB-INF, I started up tomcat. The wiki came up ok, but when trying to view the history of any page, I get the error message pasted below. I also tried clearing the DB, importing the defacto XAR file from the website then importing a backup XAR from my old load. I got the same error. I also tried running the "Fix RCS" patch overtop of both of these attempts in case it was somehow related. Again, same stacktrace. Error Message displayed (my apologies if this doesn't paste well!): Error number 4001 in 4: Error while parsing velocity page Wrapped Exception: Invocation of method 'formatDate' in class
