odd behaviour of prepared statement

this piece of code is the second PreparedStatement in a bean function.
All code before it seems to work perfectly. no amount of tinkering
with this one will avoid an SQLException "parser: parse error at end
of input" on the executeQuery();
The code executes fine in psql.
db is 7.3.2. java is sun hotspot 1.41.

Any ideas why the code fails parsing?

            ... code to process resultset.

TIP 9: the planner will ignore your desire to choose an index scan if your
      joining column's datatypes do not match
