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obsolete Scala 2.8.x and has thus exposed some outdated local 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.)
