Hi, i have used hibernate orm 4.x before upgrading to 5.0.6.
After upgrading there comes an error while using the hibernate perspective in eclipse.
In the panel 'Hibernate Configurations' i select my configuration and expand it.
While selecting 'Database' the following error appears:
An internal error occurred during: "Fetching children of Database".
org.hibernate.engine.jdbc.connections.internal.ConnectionProviderInitiator.extractIsolation(Ljava/util/Map;)Ljava/lang/Integer;

if i change my classpath from 'hibernate-c3p0-5.0.6.Final.jar' to 'hibernate-c3p0-4.3.11.Final.jar' the error didn't appear.

But why appears the error? Is there a solution, for not combining different versions, or is there no side-effect using hibernate-core-5.0.6 and hibernate-c3p0-4.3.11?

If this post is in the wrong place, pleace move it.

best regards
