The scalac plugin requires a rebuild:
org.gjt.sp.util.IOUtilities.closeQuietly(Ljava/io/InputStream;)V has been changed to org.gjt.sp.util.IOUtilities.closeQuietly(Ljava/io/Closeable;)V which is source but not binary compatible.

So all this needs is a rebuild? No code changes?

It would only need a rebuild to solve this problem.
Other problem are scala 2.7.5 is too old to compile with java 8, jetty-6.1.19.zip is nowhere to be found, so the plugin doesn't build anymore.
Code is at https://github.com/vseryakov/scalac-jedit

i fixed the plugin code up abit, to compile and load with latest jedit, and to include build instructions:
https://github.com/hoijui/scalac-jedit
(related pull request is here:
https://github.com/vseryakov/scalac-jedit/pull/2 )

it still fails to compile when used in jEdit though -> help appreciated! (i have zero scala experience)

and btw: it seems to be very rudimentary
