 * <B>Assertion Description: </B> A JDO implementation including
 * javax.jdo.query.JDOQL.bitwiseOperations in the result of PMF.supportedOptions() supports JDOQL
 * queries that contain bitwise operations. Then the integral binary bitwise operators (<code>
 * ampersand and | and ^</code>) are supported for the following types:
 *
 * <UL>
 *   <LI><code>byte, short, int, long, Byte, Short Integer, Long</code>
 * </UL>
