activity-modeler web app throwing error (activiti-5.0.beta2)

Hi, I just downloaded activiti-5.0.beta2 version of the Activiti and tried to run the demo.setup ant task. The activity-modeler web app seems to be throwing the following error.SEVERE: Null component Catalina:type=JspMonitor,name=jsp,WebModule=//localhost/activiti-modeler,J2EEApplication=none,J2EES

We test it on both jdk 5 and 6, so it must be something else.
Can you give more details on your environment (os, jdk version, web container) ?

I tried it with the following version of the JDK and the Web Container.

1. C:\Java\jdk1.5.0_17
2. C:\Java\jdk1.6.0_20
3. ant-1.7.0
4. activiti\activiti-5.0.rc1\apps\apache-tomcat-6.0.29

I tried the latest version with the same result.
I see the following line towards bottom of the log after executing
ant demo.setup task

deploy.activiti.modeler.into.tomcat:

internal.download.activiti.modeler:
     [echo] This could take a while. Set the 'skip.deploy.activiti.modeler' property in user.home/.activiti/build.proper
ties to skip this step
      [get] Getting: http://activiti.org/downloads/activiti-modeler-5.0.rc1.war
      [get] To: C:\myprograms\activiti\downloads\activiti-modeler-5.0.rc1.war

     [copy] Copying 1 file to C:\myprograms\activiti\activiti-5.0.rc1\apps\apache-tomcat-6.0.29\webapps

It seems like that the 'activiti-modeler-5.0.rc1.war' has class files compiled with JDK 1.6 whereas the class files in the version of the tomcat had been compiled with JDK 1.5. Therefore, when tomcat WebappClassLoader (compiled with version JDK 1.5) is trying to load this class
com/signavio/platform/listeners/EntryPoint (compiled with JDK 1.6) and throwing the
'bad major version at offset=6' error.

I may be missing something obvious but it seems like this will never work. Am I using wrong version of tomcat. This is the version of tomcat that was automcatically downloaded and installed by the demo.setup task.

Please advise.
