This bug was already fixed in Xenial on version 8.0.32-1ubuntu1.9:
tomcat8 (8.0.32-1ubuntu1.9) xenial; urgency=medium
* d/p/fix-class-resource-name-filtering.patch: Fix class and resource name filtering in WebappClassLoader (LP: #1606331).

And it also seems a dup of LP #1606331. I am updating the status of this bug to Fix Released in Xenial.
