 * @summary converted from VM Testbase nsk/jvmti/RedefineClasses/redefclass006.
 * VM Testbase keywords: [quick, jpda, jvmti, noras, redefine]
 * VM Testbase readme:
 * DESCRIPTION
 *     This test checks that the JVMTI function RedefineClasses()
 *     properly returns the error JVMTI_ERROR_NULL_POINTER:
 *     "Invalid pointer: classDefs or one of class_bytes is NULL".
 *     The test creates a dummy instance of tested class redefclass006r.
 *     Then the test tries twice to redefine the class redefclass006r by
 *     sequencely invoking the function RedefineClasses() with:
 *      - NULL pointer to the field class_bytes of the structure
 *        JVMTI_class_definition;
 *      - NULL pointer to the structure JVMTI_class_definition by itself.
 * COMMENTS
 *     Ported from JVMDI.
