You are correct. I skimmed over the patch quickly and made a (serious)
mistake. Apologies.

Are those exceptions worth logging? (or even worth stopping and showing
an error to the user?)

Same reason that it's better to use something that already exists rather
than re-implementing it: it has been tested more (by more people), it
has an API that more people are familiar with, and it should be more
capable and generic than something we specifically develop for icedtea-web.

That last point may be a downside too - the API may not be exactly what
we need.

I am looking forward to an updated patch. Please do include unit tests
too (as much as possible).

Thanks,
Omair
