[kepler-dev] Problems with Eclipse Install

Hello Ken,
I installed Kepler few months ago and it worked fine with Eclipse until
yesterday.
Yesterday I checked-out the newest available source code from CVS.
Now I'm getting EXACTLY the same eleven errors you're getting when you build
the project.
An update of JDK from 1.5.11 to 1.5.13 did not help.
I'm using Eclipse 3.1.2

Despite the errors, Kepler runs, displays the actors tree and executes
(simple) workflows. I don't understand that. Basic classes in Ptolemy seem
to be affected. Perhaps I will get stuck later, with more complex workflows.

Tonight I will be trying to create an independent project with my own
actors, then see whether I'm able to use them. Before, under the old version
of Kepler, I played (successfully) with the beginner's actors (HelloWorld,
Scale, etc) Afterwards I wanted to develop specific actors within a new
directory. The first actor did not appear in the tree. It had a kar file,
though. So, I decided to update Kepler... now I got in trouble again :)

Please, let me know if you will figure out a solution!!
Same kind request to the developers of Kepler....

Thank you very much,
Izabell
