Is this reproducible with a more recent version of H2? If yes could you post a
simple, standalone test case that reproduces the problem? It would be great if 
the
test case does not have any dependencies except the H2 jar file (that is, a 
simple
SQL script that can be run in the H2 Console, or a Java class uses the JDBC API 
and
is run using a static main method). Please include any initialization code 
(CREATE
TABLE, INSERT and so on) in the Java class or in a .sql script file.

Just the stack trace is not a valid bug report. See my comments.
