More likely it is the fact that you do not have a space between "END" and

In certain situations there can be a problem using dollar-quoting with JDBC
- mainly in regards to JDBC-compliant escaping but I do not recall the
specifics at the moment - but a straight literal $$...$$ block works just
fine.
