The root of the problem seems to be in your incorrect configuration. See the original exception: com.mysql.jdbc.exceptions.MySQLSyntaxErrorException: Table 'db288847.contact' doesn't exist The JdbcRowSetImpl seems to be in an incosistent state after this exception and the additional NullPointerException is probably result of this incosistence.
