Exception thrown by debug trace code: ComponentType toLoggableString
--------------------------------------------------------------------
Key: HHH-3148
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3148
Project: Hibernate3
Issue Type: Bug
Affects Versions: 3.2.6
Environment: Hibernate 3.2.6.ga
HibernateAnnotations 3.3.0.ga
Oracle 10g Express Edition
Reporter: Pete Geraghty
Priority: Minor
Attachments: ToLoggableStringExample.txt
The method toLoggableString in ComponentType is used to provide tracing output when
running with log level DEBUG. In some circumstances it throws a ClassCastException.
This is not a good idea in tracing code and obscures underlying problems.
In my case the underlying problem was a previous incorrect call to set a parameter value
in a query. I saw that previous JIRA issues have mentioned this ClassCastException as a
side effect of other underlying problems - it is a distraction and time-waster.
Lines 375-378 read:
EntityMode entityMode = tuplizerMapping.guessEntityMode( value );
if ( entityMode == null ) {
throw new ClassCastException( value.getClass().getName() );
}
A better solution would be to just us String.valueOf
EntityMode entityMode = tuplizerMapping.guessEntityMode( value );
if ( entityMode == null ) {
return String.valueOf(value);
}
Another possibility would be to concatenate some diagnostic message with String.valueOf,
but personally I don't think that be helpful.
Stack trace is:
Exception in thread "main" java.lang.ClassCastException: java.lang.String

Adam Kaplan commented on HHH-3148:
----------------------------------
Seriously, if String.valueOf() can be used, please do so...The fact that this exception is
triggered by debugging really adds a level of confusion to devs who may encounter it while
fixing something more serious!

Andreas Katzig updated HHH-3148:
--------------------------------
Attachment: NullableType.java
Create another Package org.hibernate.type in your project/cp and include the fixed
NullableType Class attached.
Applies at least for 3.2.6.
Fixed method in this file is:
public String toLoggableString(Object value, SessionFactoryImplementor factory) {
return value==null ? "null" : String.valueOf(value);
}
Originally was:
public String toLoggableString(Object value, SessionFactoryImplementor factory) {
return value==null ? "null" : toString(value);
}

------------------------------------
I think Andreas's fix may be to a different problem in a similar vein?
NullableType.java is not on the stack for the ClassCastException I reported.

------------------------------
Using 3.2.4 sp1 here.
I was getting the ClassCastException when using property-ref in a set. I got one
stacktrace leading back to this code with debugging and another stacktrace with logging
turned off.
Changing ComponentType to use String.valueOf(value) instead of throwing an exception
worked for me to see the real exception which was "Caused by: java.sql.SQLException:
ORA-00904: "RUNWAYS0_"."ID": invalid identifier".
ClassCastException was completely misleading.
I could be wrong, but it appears this was added Feb 21, 2005:
http://viewvc.jboss.org/cgi-bin/viewvc.cgi/hibernate/core/tags/v324sp1/sr....
There are multiple issues filed for this particular problem, HHH-2052, for example.
