WLS 10.3.2 - stack during commit transaction - application after upgra

[KrzysztofP]

After upgrading our application from Weblogic 8.1.4 to 10.3.2 and Java from 1.4.02_08 to 1.6.0_16 i have error during commit transaction.
On WLS 8.1.4 I had no problems. Error occurs, when client finishes his work, lists of created, modified and deleted objects are passed to server.
The server has to perform transaction commit. But the transaction isn't commited, because of the error.
Our investigation revealed, that problem occurs when we set relation between 2 beans.
In our case bean TestBean has 2 relations with 2 others beans (TestRelationBean and TestOperationBean).
When we set one of this relation there is no problem (setting relation between TestBean and TestRelationBean), but when we set another there is an error.
Related beans and relations look identical (same hierarchy and structure), but error occurs only when we set relation between TestOperationBean and TestZapisuBean.
Java sources are the same - builded on Java 1.4.02_08 and installed on WLS 8.1.4 - application works, builded on Java 1.6.0_16 and installed on WLS 10.3.2 don't.
