Fatal Exceptions During RC Startup. Is this normal?

[caryden]

Using AS Dolphin and fully updated Control Hub, when the RC starts the log has several fatal exceptions. After this, everything seems to work, but it is discomforting. Is this normal?

And there are several others.

According to https://ftctechnh.github.io/ftc_app/doc/javadoc/index.html the LegacyModule code is for the Modern Robotics Core Legacy Module, which allowed legacy hardware back from the NXT/Samantha Module days to be used with the Modern Robotics system. None of that has been relevant for many years, it looks like some code just wasn't properly deleted. Should be a simple fix, hopefully they get it properly removed for 8.2 (though it's not hurting anything currently). Not sure what's up with the others, they don't look fatal though.
