You need to update the auxiliary jedit_build component, which is 
http://www4.in.tum.de/~wenzelm/test/jedit_build-20110622.tar.gz for 
Isabelle/93dcfcf91484.  Also make sure that any old "jedit" and 
"jedit_build" components are disposed.


Since isatest now includes a full build of Isabelle/Scala and 
Isabelle/jEdit, you can get this jedit_build version information by 
watching the $MAKEALL spot in Admin/makedist, e.g. here 
http://isabelle.in.tum.de/repos/isabelle/file/93dcfcf91484/Admin/isatest/isatest-makedist#l62

Of course, you can also just download the snapshot from 
http://isabelle.in.tum.de/devel/

This is OK.

I have recently learned about JVM "extensions" and eliminated the user 
CLASSPATH, to enable things like our own encoding at the lowest possible 
level.  See also http://isabelle.in.tum.de/repos/isabelle/rev/d477b92109b8

It has also reduced the jar volume by several MB, since certain libraries 
are now provided in exactly one copy, independently how smart applications 
like jEdit change the class loader hierarchy.
