Bug ID: 59608
Summary: Manifest scanning should handle errors in resolving
entries
Product: Tomcat 8
Version: 8.0.35
Hardware: PC
OS: Linux
Status: NEW
Severity: regression
Priority: P2
Component: Util
Assignee: dev@tomcat.apache.org
Reporter: andreas.k...@gmail.com
https://bz.apache.org/bugzilla/show_bug.cgi?id=59226 added scanning of the
Class-Path JAR manifest entries (Yay!).
Unfortunately this now broke my Tomcat setup when updating from 8.0.33 to
8.0.35, I now see these errors in the logs:

I was able to track this down to a bug inside Batik 1.7
(https://bz.apache.org/bugzilla/show_bug.cgi?id=51908), but I'm pretty tied to
that version at this moment.
1. I think it would be a good idea to log the JAR name/path/URI that is
currently processed, so that finding these problems would not require stepping
through Tomcat :)
2. Given that things worked before without these entries being read, it seems
like Tomcat should catch exceptions here, and just log them as warning. For
Tomcat 9 one might be more aggressive, but for 8.x this failure mode seems to
be to aggressive.
