 * @test
 *
 * @summary converted from VM Testbase nsk/jvmti/RedefineClasses/redefclass016.
 * VM Testbase keywords: [quick, jpda, jvmti, noras, redefine]
 * VM Testbase readme:
 * DESCRIPTION
 *     The test exercises JVMTI function RedefineClasses(classCount, classDefs).
 *     The test creates a child thread which assigns a value returning
 *     by volatileMethod call to localVar in a loop. The test sets
 *     breakpoint to volatileMethod call and starts the thread.
 *     Catching breakpoint the test checks if a localVar contains correct
 *     value, then redefines the thread's class and revives the breakpoint.
 *     The redefined volatileMethod returns a new value to be assigned
 *     to the localVar.
 * COMMENTS
 *     This is a regression test on the following bug:
 *         4724076 Redefine does not work in for/while loop
 *     Fixed according to 4775012 bug.
 *     Ported from JVMDI.
