---------------------------------------------------------------------
        Key: HB-527
    Summary: Session.find throws ClassCastException when composite id is used and Class not Serializable
       Type: Improvement

     Status: Closed
   Priority: Minor
 Resolution: FIXED

    Project: Hibernate2
 Components: 
             core
   Fix Fors:
             2.1 final
   Versions:
             2.1 rc1

Environment: Hibernate 2.1 rc1, Oracle 8.1.7

Description:
Loader.java (line 347)

resultId = (Serializable) idType.nullSafeGet(rs, suffixedKeyColumns[i], session, null); //problematic for <key-many-to-one>!

The API docs say that session.find(String query) throws only a Hibernate Exception.  The ClassCast Exception is thrown and perhaps can be avoided by using isAssignableFrom(java.io.Serializable.class) first and throwing a HibernateException describing that the class doesn't implement Serializable when it should.  (This took me a while to figure out before actually going into the hibernate source code to find the source of the error)

I apologize if this bug is already known, however, I do not have time to cruise through the bug reports.  Hibernate is a godsend.  Keep up the good work! ;)
