Thanks! I was building with java6. Don't know if that is the issue. Anyway, I tested the snapshot, and looks like that fixes it.
Any idea when 4.1.0 will be released? Do you know if http://svn.apache.org/viewvc?view=revision&revision=1421958 will apply cleanly onto 4.0.3? Otherwise, how stable do you think is 4.1.0-SNAPSHOT?
