It seems to be because ClassNotFoundException is importing
ObjectInputStream. This looks  odd to me, as if someone accidentally
pasted some code in there.

Getting rid of the ObjectInputStream dependency should fix it for now at
least, but the problem may come back when Configuration.java is used more
extensively. One fix would be to put a dummy Configuration.java into the
source tree which the checks can use, then make sure that
Configuration.java is built first so that the real build doesn't
accidentally pick up the dummy version.
