Eron Wright commented on FLINK-6606:
-------------------------------------
I have a fix ready and will open a PR soon. The fix wraps all calls to the
hook such that the thread's context classloader is set to the user classloader.
> Create checkpoint hook with user classloader

> Flink should set the thread's classloader when calling the checkpoint hook
> factory's `create` method. Without that, the hook is likely to fail during
> initialization (e.g. using ServiceLoader).
