Answer 1

Thank you @BalusC. Had same issue. Tried many options. Thought this is because of lib I added to maven without prototype scope and as a result it went to war file as well, corrected, same result. I can open it as a zip and all "looks" good there.

Tried locally (different tomcat version: 7.0.67 versus 7.0.22 I have the issue with) works good. Then tried with 7.0.22 but on different VM (instance) - works good. I suspect there is something with tomcat or probably conflict with other was files (that is only difference with other VM, all including Java is same).

The issue is resolved for me using different tomcat instance.
