When zinc analysis parsing fails and print exception stacktrace is false, the resulting message is hard to understand

[baroquebobcat]

For example, if the analysis file is empty, you get the following error message.

FAILURE: Unrecognized version line:

I'm not quite sure what the behavior should be though.

One thing I'd like to move towards would be to try to make errors like this more actionable. For example, this might to be resolved by either ./pants clean-all or rm -rf .buildcache; ./pants clean-all, depending on whether the analysis files are in the buildcache entry as well.

This will be addressed in #4477
