Problem summary

****************************************************************
* USERS AFFECTED:  IBM WebSphere Application Server Liberty    *
*                  users of JavaServer Faces (JSF) MyFaces 2.0 *
*                  and 2.2                                     *
****************************************************************
* PROBLEM DESCRIPTION: The JSF feature can throw a             *
*                      java.lang.StringIndexOutOfBoundsExcepti *
*                      on while determining resource versions  *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
A StringOutOfBoundsException can be thrown from the JSF code in
certain resource loading conditions.  The exception is caused by
an error in JSF code that determines resource versions.

For example, the following param-value can cause a
StringOutOfBoundsException to be thrown during resource
loading:

<context-param>
<param-name>javax.faces.WEBAPP_RESOURCES_DIRECTORY</param-name>
<param-value>/META-INF/resources</param-value>
</context-param>

throws:
java.lang.StringIndexOutOfBoundsException: String index out of
range: 35
at java.lang.String.substring(String.java:1377)
at
org.apache.myfaces.shared.resource.ExternalContextResourceLoader
.getResourceVersion(ExternalContextResourceLoader.java:81)
...

Problem conclusion

The JSF 2.0 and JSF 2.2 features were updated to avoid throwing
the StringOutOfBoundsException.
