          Priority: P2
            Bug ID: 53681
          Assignee: general@xmlgraphics.apache.org
           Summary: [PATCH] Improve exception handling when loading
                    classpath resources fails
          Severity: minor
    Classification: Unclassified
          Reporter: dominik.stadler@gmx.at
          Hardware: PC
            Status: NEW
           Version: 1.4
         Component: utilities
           Product: XMLGraphicsCommons

I had one invalid .jar file where signing information was not correct. XML
Graphics Commons 

When calling ClasspathResource.loadManifests(), via
ClasspathResource.getInstance(), it correctly fails with a
"java.lang.SecurityException: Invalid signature file digest for Manifest main
attributes", however it does not tell me which actual jar-file could not be
loaded.

Please enhance exception handling in that method so that it reports which
jar-file failed, e.g.
