RE: [p2-dev] undeclared exception being thrown in 3.4.1

John, why isn't monitor.setCancelled used for that?

As a general rule, you should expect the possibility of
OperationCanceledException from any API method in Eclipse that takes a
progress monitor argument. This is how cancelation is propagated back to
whoever passed in a progress monitor in the first place (typically the
UI).

undeclared exception being thrown in 3.4.1

	




Ciao @ll :)
One of our clients is getting an OperationCanceledException returned by
SimplePlanner.updatesFor, well, it's really coming from
ECFMetadataTransport.getLastModified but the exception does only reach
client code at that point.

Is this an already known thing or would you want me to raise a bug on
it? All I would ask for is declaring the points where this problem with
the internet connection can happen so that we have a chance of catching
it...
