Description

The methods in org.apache.flink.api.connector.source.Source have inconsistent exception signatures:

• the methods to create reader and enumerator do not throw a checked exception
• the method to restore an enumerator throws an IOException.

Either all methods should allow throwing checked IOExceptions or all methods should not allo any checked exceptions.
