Show Project Groups page errors when using oracle as the database.

javax.jdo.JDODataStoreException: Error executing JDOQL query "SELECT THIS.PROJECT_GROUP_ID_OID AS projectGroupId,THIS.PROJECTSTATE AS projectState,COUNT(THIS.PROJECTSTATE) AS size FROM PROJECT THIS GROUP BY THIS.PROJECT_GROUP_ID_OID,THIS.PROJECTSTATE" : ORA-00923: FROM keyword not found where expected . NestedThrowables: java.sql.SQLException: ORA-00923: FROM keyword not found where expected.

The column alias "COUNT(THIS.PROJECTSTATE) AS size" should be changed since "size" is a reserved keyword. The query executes fine if it is modified to "COUNT(THIS.PROJECTSTATE) AS projectSize"
