I can add something like:

I agree. Maybe s/later/in the "catch (Throwable ex)" a few lines below"/, to
be more specific.
Thanks, updated in place.
The revised comment is a bit more verbose than my taste, but it's fine as it is.
The main point is to alert the reader that something unusual is going on.
[from John]
I think the throw-to-catch is good here, unusually, because it funnels all
BSME-wrapped
exceptions through one point. That may make somebody's day easier when placing
breakpoints.
Agreed. This approach is indeed unusual, but I think the alternatives are worse:
either the BSME wrapping can be replicated at the point of the throw, or it
could be refactored into a common method. Either seems like a step in the wrong
direction. Once you figure out this code, it isn't so bad; it's just unusual.
