Hello,

it seams that "drools-5.1.1-src.zip\drools-persistence-jpa\src\main\java\org\drools\persistence\processinstance\ProcessInstanceInfo.java" and "drools-5.1.1-src.zip\drools-persistence-jpa\src\main\java\org\drools\persistence\session\SessionInfo.java" needs to be updated so that they can be compatible with Hibernate 3.6.x.

@Lob
@Type(type="org.hibernate.type.PrimitiveByteArrayBlobType") // I think this has to be added
private byte[] rulesByteArray;

@Lob
@Type(type="org.hibernate.type.PrimitiveByteArrayBlobType") // I think this has to be added
private byte[] processInstanceByteArray;
