I left a couple comments (in tests), where the replacement code isn't
equivalent.

This will now catch and ignore runtime exceptions as well, where it previously
would cause the test to fail. This could end up missing a real problem. The two
additional checked exceptions, along with any runtime exceptions, should cause
the test to fail. In fact, I don't know why the existing exceptions are ignored
(unless there is a compelling reason to ignore them that I'm not aware of), so
probably the best thing to do would be to eliminate the try / catch entirely,
and instead add a `throws Exception` to the method declaration.

This isn't quite equivalent, since it will now wrap a `RuntimeException` in a
`LoadException`, but I think that's OK in this case.

This could re-wrap a `RuntimeException` needlessly, but is OK in this case
(it's a test and it won't change whether or not it fails). The more equivalent
fix would be to either list the checked exception individually, or to add a
`catch (RuntimeException)` before the `catch (Exception)` and re-throw the rte
without wrapping it.
