> 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 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
>     at java.base/java.lang.String.substring(String.java:2628)
