/**
|
|
* This test is from the group of so-called Borland's scenarios and
|
|
* implements the following test case: <br>
|
|
* Suite 3 - Hot Swap <br>
|
|
* Test case: TC9 <br>
|
|
* Description: Breakpoints updated correctly <br>
|
|
* Steps: 1.Set breakpoint at lines 36 and 39 <br>
|
|
* (printing 1 and 4) <br>
|
|
* 2.Debug Main <br>
|
|
* X. Stops on line 36 <br>
|
|
* 3.Delete line 37 <br>
|
|
* 4.Smart Swap <br>
|
|
* X. Breakpoints still set and valid at 36 <br>
|
|
* and 38 <br>
|
|
* 5.Resume <br>
|
|
* X. Stops on line 38 <br>
|
|
* <br>
|
|
* The description was drown up according to steps under JBuilder.
|
|
*
|
|
* Of course, the test has own line numbers and method/class names and
|
|
* works as follow:
|
|
* When the test is starting debugee, debugger sets breakpoints at
|
|
* the 47th and 49th line (method <code>method_C</code>).
|
|
* After the first breakpoint is reached, debugger redefines debugee
|
|
* deleting 48th line and attempts to set another breakpoint at 49th line.
|
|
* Because line number info is not available after redefining, it is
|
|
* expected IndexOutOfBoundsException will be thrown.
