I initially had some build problems, which I post here in case other 
people experience the same:

* It was important that scala-2.8.1.final is initialized before 
jedit_build-20110521. I initially got this wrong, which resulted in a 
broken build.

* Fixing the situation involved swapping the respective lines in my 
~/.isabelle/etc/components, and ensuring that everything is really built 
from scratch. In particular, I had to

  - remove the jars from $ISABELLE_HOME/lib/classes
  - remove the jedit-4.3.2... directory from the jedit_build component 
directory.
