-/**
- *
- * Test of the Callable
- *
- * In this test {@link DateFormatCallable} is used by 4 threads in parallel
- *
- * After a successful run 5 date values should be in the result object of each thread. All dates
- * should have the same value (15.11.2015). To avoid problems with time zone not the date instances
- * themselves are compared by the test. For the test the dates are converted into string format DD.MM.YYY
- *
- * Additionally the number of list entries are tested for both the list with the date values
- * and the list with the exceptions
