| * <B>Assertion Description: </B> If an implementation supports nontransactional read, then a call |
| * to <code>Transaction.setNontransactionalRead</code> with a parameter value of <code>true</code> |
| * will set the flag to <code>true</code> and allows persistent instances to be read outside of a |
| * transaction. Queries and navigation will be allowed without an active transaction. |
