------------------------------------
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.
