[hibernate-dev] Incompatibilites between hibernate-core 3.5.0-Beta-2 and hibernate-annotations 3.4.0GA

[Guenther Demetz]

//Hi hiberante-developers,

I don't understand exactly what the statement "*/Bundled with Hibernate 
Core as of 3.5.x" /*/(see below/) means, but I'd like to point out that 
there are several*
*incompatibilities between hiberante3.jar (3.5beta2) and 
hibernate-annotations.jar + hibernate-commons-annotations.jar (3.4.0GA).
This because of overlapping classes with different signature (please see 
exceptions below)
The environment with 3.5beta2 works correctly only if in the classpath 
hiberante3.jar preceeds the other 2 jars.
Please ignore this post in case the problem is already known

best regards
G.D.
