public class ConcurrentRuntimeException extends RuntimeException
An exception class used for reporting runtime error conditions related to accessing data of background tasks.

This class is an analogue of the `ConcurrentException` exception class. However, it is a runtime exception and thus does not need explicit catch clauses. Some methods of `ConcurrentUtils` throw `ConcurrentRuntimeException` exceptions rather than `ConcurrentException` exceptions. They can be used by client code that does not want to be bothered with checked exceptions.
