------------------------------------

             Summary: FacesConfigurator  last modified from .taglib.xml causes IndexOutOfBoundsException
                 Key: MYFACES-3958
                 URL: https://issues.apache.org/jira/browse/MYFACES-3958
             Project: MyFaces Core
          Issue Type: Bug
    Affects Versions: 2.2.7
         Environment: TomEE 1.7.1 with upgraded myfaces
            Reporter: Karl Kildén


Hello,

This has changed in 2.2.7 and it seems broken for me. 

Steps to reproduce:

1. Have no extra faces-config, just the std one in web-inf
2. Do have extra taglib.xml file!
3. It blows up on first request


The flow is like this, in FacesConfigurator#getLastModifiedTime you get a list back that is
empty if no extra faces-configs. Happens on line 378.

Then a major bad thing happens. The comment on line 389 seems aware that the call call to
#getStringInitParameter with key javax.faces.FACELETS_LIBRARIES is actually about taglibs.
However the result from that call is treated like faces-configs.

Since the list of faces-configs was empty since before it blows up on row 397. 

I don't understand the code here fully - but this is my conclusion thus far.
