What's an example of a worst case error? Is it possible to distinguish
them from other errors that are normally handled elsewhere? For
example, I see that connection loss can be caught here and by Curator
API calls in other threads at the same time.
Thanks for your help.

It’s not really very useful. I put it in there in the unlikely case
that someone wanted to handle a worst case error. The errors get
logged regardless.

Hi,
I am trying to decide whether I need to add an UnhandledErrorListener to
my Curator application in order to guarantee graceful handling of
connection loss or other failures.
At http://curator.apache.org/errors.html, I see the following paragraph:
"UnhandledErrorListener is called when a background task, etc. catches
an exception. In general, Curator users shouldn't care about these as
they are logged. However, you can listen for them if you choose."
What is the purpose then of an UnhandledErrorListener? Is it purely for
any custom logging that a Curator user might wish to perform? Are there
any known use cases where it is worthwhile to catch and handle
exceptions in some other manner here?
Thanks.
Joel
