Mastodon Exceptions Occurred During Plugin Discovery

[allyrp]

When opening Mastodon and trying to open a file I am getting these errors. Looking for some solutions to the problem.

[WARNING] 1 exceptions occurred during plugin discovery.

Hello.
It seems like a conflict between beta-26 and beta-28 classes.
Can you truy the following:
1/ Try installing Mastodon on a freshly downloaded Fiji, with no other update-sites subscribed.
2/ Can you list the mastodon-*.jar files you have in the jars/ folder of the culprit Fiji install?
