Why does UmbrellaException have that name?

问题

I'm working with GWT and sometimes I'm getting exception called UmbrellaException I was always wondering why is it called like that? It is because there is a lot of error (rain) that you have to protect the application (use umbrella not to get wet).

回答1:

According to the first link when i googled the term "gwt umbrellaexception":

A RuntimeException that collects a Set of child Throwable together. Typically thrown after loop, with all of the exceptions thrown during that loop, but delayed so that the loop finishes executing.

It's just a Collection of Exception (Throwable actually). Read the API Doc for more information.

com.google.gwt.event.shared.UmbrellaException

It's a Set of all the exceptions thrown during a loop which is thrown after the loop is done. Looks like it's used to let the loop to finish even if some exceptions occur during it's execution.
