[hibernate-issues] [Hibernate-JIRA] Commented: (HHH-4825) mapping order impacting behavior leading to bug

[Strong Liu (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HHH-4825?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=35667#action_35667 ] 

Strong Liu commented on HHH-4825:
---------------------------------

two ways of fixing this I guess:
1.
open the comment below:
[http://anonsvn.jboss.org/repos/hibernate/core/trunk/core/src/main/java/org/hibernate/util/StringHelper.java]
{code}
	public static int lastIndexOfLetter(String string) {
		for ( int i=0; i<string.length(); i++ ) {
			char character = string.charAt(i);
			if ( !Character.isLetter(character) /*&& !('_'==character)*/ ) return i-1;
		}
		return string.length()-1;
	}
{code}
2. use Column.getAlias(Dialect,Table) instead of Column.getAlias(Dialect) in org.hibernate.persister.collection.AbstractCollectionPersister.AbstractCollectionPersister(Collection, CollectionRegionAccessStrategy, Configuration, SessionFactoryImplementor)
