Hi Miles and everyone,

(moving this to ajdt-dev mailing list)

I am just trying to get Scala and AJDT installed on 3.6.  The good
news is that I was able to create a Scala project, a Scala class, an
AspectJ project, and an Aspect that adds an ITD onto the scala class
(and decompilation looks like the build was successful.  However, I
cannot open the Scala editor (or the Scala class file editor).  I keep
getting variants of the following exception.

It could be that the weaving is not working properly, but more likely
it seems that the plugin is referencing a method that no longer exists
in M7.  (This is with the latest nightly build of Scala IDE.)
