+ * @test
+ *
+ * @summary converted from VM Testbase nsk/jdi/VoidValue/hashCode/hashcode001.
+ * VM Testbase keywords: [quick, jpda, jdi]
+ * VM Testbase readme:
+ * DESCRIPTION:
+ * The test for the implementation of an object of the type
+ * VoidValue.
+ * The test checks up that a result of the method
+ * com.sun.jdi.VoidValue.hashCode()
+ * complies with its spec:
+ * public int hashCode()
+ * Returns the hash code value for this VoidValue.
+ * Returns: the hash code
+ * Overrides: hashCode in class java.lang.Object
+ * The test works as follows:
+ * A debugger program - nsk.jdi.VoidValue.hashCode.hashcode001;
+ * a debuggee program - nsk.jdi.VoidValue.hashCode.hashcode001a.
+ * Using nsk.jdi.share classes,
+ * the debugger gets the debuggee running on another JavaVM,
+ * creates the object debuggee.VM,
+ * establishes a pipe with the debuggee program, and then
+ * send to the programm commands, to which the debuggee replies
+ * via the pipe. Upon getting reply,
+ * the debugger calls corresponding debuggee.VM methods to get
+ * needed data and compares the data got to the data expected.
+ * In case of mismatch the test produces the return value 97 and
+ * a corresponding error message(s).
+ * Otherwise, the test is passed and produces
+ * the return value 95 and no message.
+ * COMMENTS:

+ * The test for the implementation of an object of the type <BR>
+ * VoidValue. <BR>
+ * <BR>
+ * The test checks up that results of the method <BR>
+ * <code>com.sun.jdi.VoidValue.hashCode()</code> <BR>
+ * complies with its spec. <BR>
+ * <BR>
+ * The cases for testing are as follows : <BR>
+ * <BR>
+ * when a gebuggee is suspended at a breakpoint <BR>
+ * set by a debugger, <BR>
+ * the debugger invokes debuggee's methods: <BR>
+ * void vdValue1(); void vdValue1(); void vdValue2();<BR>
+ * to form the follwing objects: Value returnvdValue1, <BR>
+ * Value returnvdValue2, and Value returnvdValue3; <BR>
+ * <BR>
+ * performs following casts: <BR>
+ * VoidValue vdValue1 = (VoidValue) returnvdValue1; <BR>
+ * VoidValue vdValue2 = (VoidValue) returnvdValue2; <BR>
+ * VoidValue vdValue3 = (VoidValue) returnvdValue3; <BR>
+ * <BR>
+ * and checks up that each of the following is true: <BR>
+ * <BR>
+ * vdValue1.hashCode() == vdValue2.hashCode() <BR>
+ * vdValue1.hashCode() == vdValue3.hashCode() <BR>
