Solving Can't find resource for bundle com.liferay.portlet.PortletResourceBundle, key javax.portlet.title

I have seeing many of you dealing with this error.
 I spent hours reading and trying to figure out what was the problem. These are my findings ...

 Example code. (ERROR)

	<portlet>
	<portlet-name>COMMON_BACKUP_RESTORE</portlet-name>
	<display-name>Backup-Restore</display-name>
	<portlet-class>com.ng.framework.portlet.NGStrutsPortlet
	</portlet-class>
	<init-param>
	<name>view-action</name>
	<value>/ext/ng/backup_restore/view</value>
	</init-param>
	<expiration-cache>0</expiration-cache>
	<supports>
	<mime-type>text/html</mime-type>
	</supports>
	<resource-bundle>com.liferay.portlet.StrutsResourceBundle

Using Eclipse (I didn't test with another IDE) the Ctrl+Shift+F command will indent your code, but for some reason this breaks the xml
We are interested in this specific line

	<resource-bundle>com.liferay.portlet.StrutsResourceBundle
	</resource-bundle>

And should be

<resource-bundle>com.liferay.portlet.StrutsResourceBundle</resource-bundle>
