They're functionnal, but there are some "message output is null" in the
tomcat's console, and the log file contains the following exception on
the Simple SQL sample.

Couldn't this be caused by the connection being closed twice ? A quick
look to SQLTransformer did not reveal it, but maybe it could be worth
investigating this way.
