      public class ConcurrentException
      extends Exception

  An exception class used for reporting error conditions related to accessing data of background tasks.

  The purpose of this exception class is analogous to the default JDK exception class `ExecutionException`, i.e. it wraps an exception that occurred during the execution of a task. However, in contrast to `ExecutionException`, it wraps only checked exceptions. Runtime exceptions are thrown directly.

  Since:
    3.0
