/**
* This test is from the group of so-called Borland's scenarios and
* implements the following test case: <br>
* Suite 2 - Breakpoints (multiple threads) <br>
* Test case: TC2 <br>
* Description: Class breakpoint <br>
* Steps: 1.Add class breakpoint: singlethread.Class1 <br>
* 2.Debug Main <br>
* X. Stops on line 13 in Class1.java <br>
*
* When the test is starting debugee, debugger creates <code>MethodEntryRequest</code>.
* After <code>MethodEntryEvent</code> arrived, debugger checks line number of one's
* location. It should be 79th line, that is constructor of <code>tc02x004aClass1</code>
* class. Every thread must generate <code>MethodEntryEvent</code>.
*
* In case, when at least one event doesn't arrive during waittime
* interval or line number of event is wrong, test fails.
