Reproduction

Attached test case reproduces the issue in JavaSE environment. Here are steps to execute the test case
1. unzip the testcase
2. Adjust build.properties to point to your EcliopseLink workspace
3. Adjust test.properties to point to your database
4. Execute the test using "ant agent run". Observe how expected insert statements into the relationship table are not executed at end of test case

Please note that if agent is not used in above step, insert statements are executed as expected.
