[Bug 56366] New: Use case-insensitive matching in StandardJarScanner

            Bug ID: 56366
           Summary: Use case-insensitive matching in StandardJarScanner
           Product: Tomcat 8
           Version: 8.0.5
          Hardware: PC
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Catalina
          Assignee: dev@tomcat.apache.org
          Reporter: knst.kolinko@gmail.com

>From code review while working on bug 56365, the JAR scanning feature uses
case-sensitive name checks in a number of places:

a) in path.endsWith(Constants.JAR_EXT) check in StandardJarScanner#scan(..)
b) when matching file names in o.a.t.util.file.Matcher

I think it would be better to perform such checks case-insensitively.

(Does this affect QSYS.LIB on AS/400 ?)

--- Comment #1 from Mark Thomas <ma...@apache.org> ---
Section 10.5 of the Servlet spec requires that JAR files deployed as part of a
web application have an extension of '.jar'

Tomcat performs all operations relating to static files within web applicaitons
(including JAR files) in a case sensitive manner to avoid security issues
caused by mixing case sensitive and case insensitive matching even on platforms
where the file system is not case sensitive.

Note:
- The JAR file specification explicitly places no limits on the name of a JAR
file.
- File names are case sensitive on most operating systems. Windows is the major
exception.
