Tomcat6 Problem (wrong JVM)

Beware: I don't use the Ubuntu-packaged version of Tomcat, so I'm only
guessing/trying to remember from a test I did long ago.

I'd take a look at /etc/default/tomcat* if something like it exists, at
the init script itself otherwise, and see if JAVA_HOME or JRE_HOME is
set there.

My guess would be OpenJDK.
