 * @summary converted from VM Testbase nsk/jdb/redefine/redefine001.
 * VM Testbase keywords: [jpda, jdb]
 * VM Testbase readme:
 * DECSRIPTION
 * A positive test for the 'redefine <class id> <class file name>' command.
 * The debuggee program invokes three times method 'foo()' of RedefinedClass
 * class. This class in redefined with checked command each time before last
 * two invocations. If redefinitions occurs then the value returned by 'foo()'
 * method must be different from one returned previous invocation.
 * The test passes if method 'foo()' of the RedefinedClass returns expected
 * values.
 * The test consists of three program:
 *   redefine001.java - launches jdb and debuggee, writes commands to jdb, reads the jdb output,
 *   redefine001a.java - the debugged application.
 *   RedefinedClass.java - the class to be redefined.
 *   newclass_g/RedefinedClass.java - the redefining class.
