[jboss-jira] [JBoss JIRA] (AS7-5550) servlet filter mapping empty string not working

[Cheng Fang (JIRA)]

    [ https://issues.jboss.org/browse/AS7-5550?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12718418#comment-12718418 ] 

Cheng Fang commented on AS7-5550:
---------------------------------

I guess that's why the spec calls it a 'special' url pattern.  My reading is that it should apply to both servlet mappoing and filter mapping.  Say an app has filter mapping "" and servlet mapping "", and they would expect the filter to be associated with the target servelt since they have the same url pattern.  But now the filter will just be silently ignored in as7.

> The empty string ("") is a special URL pattern that exactly maps to the
