[jira] [Commented] (MYFACES-4292) String Out of Bounds Exception Thrown

["Bill Lucy (JIRA)" <de...@myfaces.apache.org>]

    [ https://issues.apache.org/jira/browse/MYFACES-4292?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16858859#comment-16858859 ] 

Bill Lucy commented on MYFACES-4292:
------------------------------------

I was able to reproduce this by following along with [https://github.com/OpenLiberty/open-liberty/issues/5898]

What's happening is a similar case to the existing comment - so I think the patch is fine.
_// This can happen if the classloader provided us a URL that it thinks exists_
_// but really doesn't.  In particular, if a JAR contains META-INF/MANIFEST.MF_
_// but not META-INF/, some classloaders may incorrectly report that META-INF/_
_// exists and we'll end up here.  Just ignore this case._

> When deploying an application, the placement of the MANIFEST.MF file in a loose application xml can cause a java.lang.StringIndexOutOfBoundsException during MyFaces initialization. This problem occurs with the following path: /tmp/war/MANIFEST.MF 
> This issue was solved in JSF 2.3 with MYFACES-4273, but not in JSF 2.2.
> By moving the catch block to the outer try block in myfaces/view/facelets/util/Classpath.java, the StringIndexOutOfBoundsException will be caught, and the  faces initialization will continue normally.  
> Stack Trace:
> Caused by: java.lang.StringIndexOutOfBoundsException: String index out of range: 0
