> We had a couple of class loading issues in the past because people forgot to use the right classloader in {{flink-table}}. The SQL Client executor code hacks a classloader into the planner process by using {{wrapClassLoader}} that sets the threads context classloader.
> Instead we should allow passing a class loader to environment settings. This class loader can be passed to the planner and can be stored in table environment, table config, etc. to have a consistent class loading behavior.
> Having this in place should replace the need for {{Thread.currentThread().getContextClassLoader()}} in the entire {{flink-table}} module.
