This is changing. Scala is getting more popular among Java people. And
this trend is visible almost within our community. Year ago I wouldn't
commit anything in Scala, now I'm waiting for another of my pull
requests to be merged into the Spring Scala [1] project. In the year
from this point forward probably more of us will adopt Scala for their
skillsets. Keep in mind also that rejecting Scala contributions will
result in rejecting the Scala people from our community. This is
Catch-22 kind of situation.

Yes it is - maintenance of Java code making use of Scala libraries not
designed to be accessed from Java is a hell. It is technically
possible, but tough in reality. This is unnecessary maintenance burden
we can easily avoid just by writing the component in Scala.

First of all Scala is bit different than ordinary scripting language,
because it is often (and successfully) considered by users as the
replacement for Java in the context of the messaging-related systems.
Also, let's say Groovy, can be integrated into Java component more
easily than Scala.

Very good point.

To summarize a little bit - I strongly believe that we as development
team can handle supporting Scala components. I also believe that
throwing away Scala contributions from our community will not be good
for it in the long run.

Best regards.
