/** | |
* Test for bug 2612366: Conform results in UnitOfWork extremely slow. | |
* <p><b>Test Description:<b> | |
* <ul> | |
* <li>Conform results test using a wrapper policy. | |
* <li>Insure that the number of times unwrap is called is linear to the | |
* number of objects read in. | |
* <li>The test input is small to allow this to be run as a short | |
* regression test. The relationship between input size and calls to unwrap is | |
* the key. | |
* </ul> | |
