Fixed. I installed the right scala version in the right place.

Which is which version and which place?

The "right" way is to take official Isabelle releases as an opportunity to re-use the included contrib components as far as feasible. The Isabelle2012 website now also has an explicit link to http://isabelle.in.tum.de/dist/ to make this easier to follow.


For the historically correct record: the changeset that discontinued obsolete Scala 2.8.x and has thus exposed some outdated local configurations is Isabelle/7700f0e9618c. It affects the src/Tools/jEdit/README_BUILD file in particular, which is usually up-to-date to say what is required to build Isabelle/Scala and Isabelle/jEdit properly.

Moreover, as seen on some other mail threads, Admin/contributed_components is becoming more and more formal and reliable in documenting extra component dependencies. (Although that file should probably be renamed to Admin/components now.)
