I agree that my suggestion would not affect run-dev since it does not build
or load kepler.jar.
My observation was based on the fact that I noticed that ...
... contained a mixture of both .java and .class files and is easily the
largest jar file. This is also the file that most first time *end users*
I also realise that the relative performance improvement of this change may
be minimal given other contributing factors but I figured that the
observation might still be useful.
