Comment 2 sinbadinux 2011-01-04 13:39:09 UTC 
The workaround i found is to use the oracle thin driver in the 'hibernate configuration wizard' I don't know if this will cause some side effects in the next development steps.

To use the oracle thin driver I selected:
1- New Hibernate Configuration Wizard;
2- In the Database connection field select: New Database Connection;
3- the New Database Connection window will be shown;
4- In the driver name I selected: New Driver;
5- the New JDBC Driver dialog will be shown;
6- click the add button and select the ojdbc6.jar which is in the folder: <oracle_path>\oracle\product\11.1.0\client_1\jdbc\lib
7- automatically the fields Driver Class and name will be filled with Oracle Thin;
8- use this JDBC Driver for the hibernate configuration.
Comment 3 Sergey Petrov 2011-02-24 18:48:13 UTC 
may be fixed with issue 194449 if classloader will be properly released after usage (but may not if it will be loaded by one classloader in services tab and second hibernate classloader).
it's good there is a workaround.
Comment 4 Sergey Petrov 2013-12-11 12:07:37 UTC 
mark as works for me as it's unclear if it was fixed, but according to latest comment it may be fixed as side effect of another issue and there are no reports after 6.9.1
