Stupid guess, but can you also check the content of your guacamole/extensions directory?

Some extensions (looking at you, TOTP) will make Tomcat crash with this exact error if multiple versions are loaded.


We should add an additional sanity check to warn if this condition is detected, but FYI:

The reason multiple copies of the same extension cannot be loaded at the same time is their namespaces will collide. Every extension defines a unique namespace to isolate itself from others. If that namespace isn't actually unique, then resources/endpoints declared by those extensions will have conflicting paths, causing webapp startup to fail.
