/*
FileName: ATEST13.java
 
The output of this example is as follows:
 Entered the testcase
 Create a thread
 Start the thread
 Wait a bit until we 'realize' the thread needs to be canceled
 Thread: Entered
 Thread: Looping or long running request
 Thread: Looping or long running request
 Thread: Looping or long running request
 Wait for the thread to complete
 Thread status indicates it was canceled
 Testcase completed
