java.lang.StringIndexOutOfBoundsException: String index out of range: -1

There seems to be a regression bug in driver 1.2.2 with the following query that raise an exception (works fine with version 1.2.0):

PreparedStatement ps = c.prepareStatement("insert into t1 (LAST_UPDATE_DATETIME, VERSION) select ?, version from t2");
ps.setTimestamp(1, new java.sql.Timestamp(System.currentTimeMillis()));
ps.executeUpdate();
