| This test failure is caused because MySQL handles only seconds
granularity for time fields.  See
org.eclipse.persistence.testing.tests.history.HistoryTestModel
buildUpdateObjectTestSuite line 104: 
 if(getSession().getPlatform().isMySQL()) {
 if(internalException.getClass().getName().contains("MySQLIntegrityConstraintViolationException"))
{
 // two objects created / updated during the
same second will have the same date/time representation
 // in MySQL database column because on
MySQL microseconds cannot be stored into a column of any temporal data
type.
 throw new TestWarningException("on MySQL
microseconds cannot be stored into a column of any temporal data type,
therefore the following exception occurred: ", internalException);
 
 Also there is a separate bug for this issue:
 
 https://bugs.eclipse.org/bugs/show_bug.cgi?id=210270
 
 So we could wrap the bug 319276 test in a
HistoryTestModel$WrappedWriteObjectTest so it throws this warning and
doesn't result in a test error or we could just fix 210270 which I'm
happy to do and would be better in terms of allowing history support on
MySQL too.
