    Comment:
This is not a bug. It is known and intended functionality. Perhaps we could provide for both property naming conventions, since the JavaBeans spec seems a bit unclear on this point.
    Changes:
             type changed from Bug
             priority changed from Critical

        Key: HB-373
    Summary: problem in the ReflectHelper leads to "could not find getter"
       Type: Improvement

     Status: Unassigned
   Priority: Minor

    Project: Hibernate2
 Components: 
             core
   Versions:
             2.0.3

Environment: Win 2000

Description:
If one has a variable like:
aEndTerminal

The getter/setter are generated corectly by the code generator, BUT:
Because the getter/setter changes aEndTerminal to AEndTerminal, we got
into this later on:

net.sf.hibernate.PropertyNotFoundException: Could not find a getter for aEndTerminal in class com.im.Trail 
at net.sf.hibernate.util.ReflectHelper.getGetter(ReflectHelper.java:206) 
at net.sf.hibernate.persister.AbstractEntityPersister.<init>(AbstractEntityPersister.java:571) 
at net.sf.hibernate.persister.EntityPersister.<init>(EntityPersister.java:665) 
at net.sf.hibernate.persister.PersisterFactory.create(PersisterFactory.java:29) 
at net.sf.hibernate.impl.SessionFactoryImpl.<init>(SessionFactoryImpl.java:207) 
at net.sf.hibernate.cfg.Configuration.buildSessionFactory(Configuration.java:627) 
at com.im.Main.initHibernate(Main.java:42) 
at com.im.Main.go(Main.java:48) 
at com.im.Main.main(Main.java:35) 
Exception in thread "main

The problem is Introspector.decapitalize() 
It has a "special case" that we're hitting, quote from javadoc: 

" This normally means converting the first character from upper case to lower case, but in the (unusual) special case when there is more than one character and both the first and second characters are upper case, we leave it alone." 

I've created a copy of Introspector.decapitalize inside ReflectHelper.java without the "special case" , replaced all calls to Introspector.decapitalize with my new 'decapitalize' and all works like a charm. 

So in my opinion Introspector.decapitalize should not be used in the RelectHelper !!!

This kind of bug surfaces when the variable begins with one single lower case character followed by an upper case character !!

Thanks,
