Subject [jira] [Commented] (LANG-769) Please restore NotImplementedException and UnhandledException
Date Tue, 24 Apr 2012 13:15:35 GMT


Jean-Noel Rouvignac commented on LANG-769:

Hi Henri,

I agree with David Cogen: these exceptions are the ones I use most!

I am using NotImplementedException to fail fast in case I did not handle a specific path in
the code when I deemed it unnecessary to handle from the start or when could not foresee changes
coming in, like a newly added values to an enum for example.
Then I am using UnhandledException to bypass the horrid checked exception in Java which is
needed just about all the time.

Please add them back, I miss them so much!

> Why were these removed? I found these very useful and used them often. As the version
2.6 api javadoc states, "This exception supplements the standard exception classes by providing
a more semantically rich description of the problem."
> Just want you to realize that these have found direct use outside the library; not just
internal use within commons-lang.
> I will define these missing classes myself, or maybe include both commons-lang and commons-lang3
(but I really don't to do that). It would be very nice to have these back.
