[jboss-jira] [JBoss JIRA] Commented: (JBVFS-143) file:// protocol URL might not work with 3rd party libraries

    [ https://jira.jboss.org/jira/browse/JBVFS-143?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12518408#action_12518408 ] 

John Bailey commented on JBVFS-143:
-----------------------------------

Actually looking at the Jetty source makes it clear the issue is with the way the file: URLs are being handled by Jetty.  It looks like the solution to this would be to use a separate URL scheme as the Jetty code, as well as most 3rd party libs, have ways to support unknown schemes.

>         }
>         return new URLResource(url,null,useCaches);
>     }
> As a consequence, content access does not work. 
> This seems to be a general issue caused by the reuse of the well known file:// protocol which may be processed explicitly by 3rd party libs.
