Problems with TestTimeoutException due to changes introduced by OPENJPA-1565.
Tests were disabled for DB2 and Oracle in r924867.
Still seeing test failures for HSQLDB, MSSQL and MySQL.
QueryTimeOut and LockTimeOut exceptions are not raised correctly
Implement LockTimeout using db specific server-side lock timeout feature
Move fix version to 2.3.0 in preparation for 2.2.0 release.
