try without catch. A Bug? [message #480838]

Hello,

i have a newbie question. I've found an try-finally construct in the
source org.eclipse.ui.views.markers.internal.ExtendedMarkersView (Method
getUpdateJob) from the org.eclipse.ui.ide plug-in.

The problem with it is, that an exception is raised if a translation is
incorrect (A incorrect format string). It produce a lots of
Error-Dialogs (once per minute ) without any stack-trace. So it is very
hard to find the incorret translation-string.

I've correct the translation-string at the babel project. But is this
also a bug in the source? Should it report this as bug?

Greeting
Kai

I would raise a bug to see if there is anything that can be done about continually opening dialogs ... it would be better if it didn't do that.

But try..finally is a java construct to ensure that code is executed (and it doesn't get in the way of the exception).

ex:
contexts.deferNotifications(true);
try {
// stuff
} finally {
contexts.deferNotifications(false);
}

This ensures that an exception from client code *cannot* put you in the state where you no longer send notifications.
