Description

Currently the JobClient interface extends AutoCloseable but provides a default, empty implementation for the close() method. This is error-prone as subclass implementations may not think that they need to actually implement a proper close().

 

To this end, this issue aims at removing the default implementation and each implementation of the JobClient will have to explicitly provide its own implementation.
