Major Description
Probably another corner case around TextProvider in connection with wildcard mapping:
Embeded elements (in URLs, image tags...) in jsp like <s:text name="edit"/> throw an NP-Exception.
struts.xml
<action name="**" class="org.package.MyClassDoingNothing"> <result name="test">/view/test.jsp</result> </action>
test.jsp contains an element like this:
<img title="<s:text name="edit"/>" alt="<s:text name="edit"/>" src="editImage.jpg"/>
This will give since 2.5.12 null pointer exception:
