[jboss-jira] [JBoss JIRA] Created: (HIBERNATE-104) useless stacktrace
useless stacktrace
------------------
Key: HIBERNATE-104
URL: https://jira.jboss.org/jira/browse/HIBERNATE-104
Project: Hibernate
Issue Type: Bug
Environment: jboss-4.2.2.GA, linux 32bit
Reporter: arne anka
Assignee: Steve Ebersole
when trying
entityManager.merge(myUser);
entityManager.flush();
i get a very long list of recurrent stacktraces. it boils down to two messages:
Caused by: org.hibernate.PropertyAccessException: IllegalArgumentException occurred

the property my.class.roleId is defined as Integer, setter and getter expect or return an
Integer.
i can't see, what type hibernate expects as argument and i can't see in what type
hibernate tries to cast.
- why does the stacktrace not mention the argument type hibernate expects?
- why does the stacktrace not mention in which type hibernate tries to cast?
with it's current level of null-information ist that _very_ long, confusing and time
consuming stacktrace worse then useless.
i am completely unable to deduce any way to remedy a possible bug in my code or circumvent
a possible bug in hibernate.
