> Discovered while working on DRILL-3927.
> The client and server both use the same direct memory allocator code. But the allocator's
OutOfMemoryException is derived from FragmentSetupException (which is derived from ForemanException).
> Firstly, OOM situations don't only happen during setup.
> Secondly, Fragment and Foreman classes shouldn't exist on the client side. (This is causing
unnecessary dependencies on the jdbc-all jar on server-only code).
> There's nothing special in those base classes that OutOfMemoryException depends on. This
looks like it was just a cheap way to avoid extra catch clauses in Foreman and FragmentExecutor
by catching the baser classes only.
