>                 URL: http://opensource.atlassian.com/projects/hibernate/browse/HSEARCH-384
>             Project: Hibernate Search
>          Issue Type: Improvement
>            Reporter: Sanne Grinovero
>            Assignee: Sanne Grinovero
>             Fix For: 3.2.0

>
> the code of Hibernate Search is very extensible, as nearly all
> internal modules are "overridable" by user provided implementation;
> this external classes are loaded by defining a short name (in case of
> built-in extensions) or fully qualified names to load
> whatever is on the classpath to replace internals.
> For some issues I'll soon have to be copy-pasting the usual exception
> handling code around, again..
> A quick regex count on the code base reveals that this same code is
> duplicated in other 25 places, mostly correct but sometimes
> forgetting to handle one or two cases (for example ClassCastException
> is not handled often)
> I am building a util class to get some consistency, and plan to unit
> test this extensively to make sure it throws understandable exceptions
> for the most common mistakes (hey, I need a public no-args
> constructor! / not implementing the X interface! / ...)
> -> DRY, improve error messages.
