  * This test is from the group of so-called Borland's scenarios and

  *     Suite 1 - Breakpoints (single threads)
  *     Test case:      TC1
  *     Description:    Line breakpoint & step into
  *     Steps:          1.Set breakpoint on line 19
  *                     2.Debug Main
  *                       X. Stops on line 19
  *                     3.Run | Step into three times
  *                       X. Steps into Class1 constructor
  *
  * When the test is starting debugee, debugger sets breakpoint at
  * the 49th line (method <code>performTest</code>).
  * After the breakpoint is reached, debugger creates "step into" request
  * and resumes debugee. <code>StepRequest</code> is created with specified
  * <code>addClassExclusionFilter</code>. For the third <code>StepEvent</code>
  * debugger checks line number of one's location. It should be 56th line.
  *
  * In case, when line number of event is wrong, test fails.
