Anthony Baker updated GEODE-2375:
---------------------------------
Issue Type: Improvement (was: Bug)
> GemFireException should not inherit from RuntimeException
> ---------------------------------------------------------
>
> Key: GEODE-2375
> URL: https://issues.apache.org/jira/browse/GEODE-2375
> Project: Geode
> Issue Type: Improvement
> Components: core, general
> Reporter: Galen O'Sullivan
> Priority: Major
>
> {{GemFireException}} inherits from {{RuntimeException}}, which means that the
> majority of exceptions in Geode are unchecked. This means that we don't have
> the type system helping us to check potential failure conditions of our code,
> and it's not clear which functions may throw exceptions as a part of their
> nomal failure modes -- for example, {{ReplyException}} has a
> {{handleAsUnexpected}} method that seems to indicate that a normal
> {{ReplyException}} is not unexpected -- but that's not what the type
> inheritance says. {{GemFireException}} accounts for most of the exceptions in
> the codebase.
> Even if we were to convert most of the existing instances of
> {{GemFireException}} to {{GemFireRuntimeException}}, developers (especially
> new ones) would still be tempted to use {{GemFireException}} for new
> exceptions.
> Perhaps the best way to solve this (if we want all our exceptions to inherit
> from a central exception type, which I'm not entirely sold on) would be to
> create a new {{GeodeUncheckedException}} and {{GeodeCheckedException}}, and
> deprecate both kinds of {{GemFireException}}? Then we could convert old
> exceptions as time permits.
> There's a significant amount of work involved here whatever way we decide to
> change it.
