 * @summary converted from VM Testbase nsk/jdi/ReferenceType/defaultStratum/defaultStratum002.
 * VM Testbase keywords: [quick, jpda, jdi, feature_sde, vm6]
 * VM Testbase readme:
 * DESCRIPTION
 *     The test checks up that default stratum specified in class file affects result of following methods:
 *         - ReferenceType.defaultStratum()
 *         - ReferenceType.sourceName()
 *         - ReferenceType.allLineLocations()
 *         - ReferenceType.locationsOfLine(int lineNumber)
 *     Debugger creates copy of class file for class 'nsk.share.jdi.TestClass1' with SourceDebugExtension attribute
 *     which contains informations for 3 stratums('TestStratum1'-'TestStratum3') and for each of this stratums following line mapping
 *     is defined:
 *         "Java"          "TestStratum"
 *         <init>
 *         9       -->     1000, source1
 *         10      -->     1001, source1
 *         ...             ...
 *         16      -->     1007, source1
 *         sde_testMethod1
 *         20      -->     1100, source1
 *         21      -->     1101, source1
 *         ...             ...
 *         27      -->     1107, source1
 *         sde_testMethod1
 *         31      -->     1200, source1
 *         32      -->     1201, source1
 *         ...             ...
 *         38      -->     1207, source1
 *     Stratum 'TestStratum1' is specified as default for 'TestClass1'.
 *     Then debugger forces debuggee to load 'TestClass1' from updated class file, obtains ReferenceType for this class
 *     and checks up that following methods:
 *         - ReferenceType.defaultStratum()
 *         - ReferenceType.sourceName()
 *         - ReferenceType.allLineLocations()
 *         - ReferenceType.locationsOfLine(int lineNumber)
 *     returns information for 'TestStratum1'.
