Subject [jira] [Commented] (OAK-89) Improve exception handling
Date Tue, 08 May 2012 10:07:51 GMT

    [ https://issues.apache.org/jira/browse/OAK-89?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13270346#comment-13270346

Michael Dürig commented on OAK-89:
----------------------------------

Thinking a bit more about this, I'm fine with using checked exceptions. However, in that case
we *should not* use a common base exception because this would defy the initial reasoning
for using checked exceptions: it would easily result in code where the base exception could
be thrown by virtually every method and "we'll just end up treating it as a generic "I can
just throw this without worrying about the design consequences" -exception" as was Jukka's
concern for unchecked exceptions. 

We should rather use very specific exceptions which have a very limited local scope.

and handled. 
> I suggest to create a OakException which extends from RuntimeException and encapsulate
a RepositoryException into it. These exceptions can then be handled where appropriate. We
can the later turn this into a more sophisticated mechanism where the OakException is mapped
to a corresponding RepositoryException by an injected mapping (see Jukka's proposal in the
discussion).
