 * @summary converted from VM Testbase nsk/jdi/StepEvent/_itself_/stepEvent003.

 * DESCRIPTION
 *     The test checks up that StepEvents are generated correctly if SourceDebugExtension defines following line mapping:
 *         "Java"          "Test stratum"
 *         line 1  -->     line 1, source 1
 *         line 2  -->     line 1, source 2
 *         line 3  -->     line 1, source 3
 *     (lines in "Test stratum" has same numbers but different sources)
 *     Debugger creates copy of class file for class 'nsk.share.jdi.TestClass1' with SourceDebugExtension attribute
 *     which contains informations for 1 non-Java stratum and for this stratum following line mapping is defined:
 *         "Java"          "TestStratum"
 *         <init>
 *         32      -->     1000, source1
 *         33      -->     1000, source2
 *         ...             ...
 *         sde_testMethod1
 *         43      -->     1100, source1
 *         44      -->     1100, source2
 *         ...             ...
 *         sde_testMethod1
 *         54      -->     1200, source1
 *         55      -->     1200, source2
 *         ...             ...
 *     Then debugger forces debuggee to load 'TestClass1' from updated class file, starts event listener thread which saves all received StepEvents,
 *     enables StepEvent request(class filter is used to receive events only for 'TestClass1') and forces debuggee to execute all methods defined in 'TestClass1'.
 *     When all methods was executed debugger checks up that StepEvents was generated for each location specified for 'TestStratum'.
