[hibernate-issues] [Hibernate-JIRA] Commented: (HBX-1116) Generated hashCode() is inconsistent with equals() when using natural-id tag

[Magnus Jungsbluth (JIRA)]

    [ http://opensource.atlassian.com/projects/hibernate/browse/HBX-1116?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=32780#action_32780 ] 

Magnus Jungsbluth commented on HBX-1116:
----------------------------------------

after the patch generated hashCode() looks like:

	public int hashCode() {
		int result = 17;
         
		result = 37 * result + ( getIdentificationNo() == null ? 0 : this.getIdentificationNo().hashCode() );
		return result;
	}

> when using a natural-id tag in a hbm.xml file, the pojo's generated equals method uses the natural-id properties while the hashcode implementation requires an additional meta-attribute
> the included patch uses the same check as in the equals generation in basicpojoclass.java
> additionally the template has been changed to only iterate over equalshashcode properties which reduces unnecessary blank lines in the hashcode implementation
> the template also contained wrongly indented lines
