31  * DECSRIPTION
32  * A positive test for the 'redefine <class id> <class file name>' command.
33  * The debuggee program invokes three times method 'foo()' of RedefinedClass
34  * class. This class in redefined with checked command each time before last
35  * two invocations. If redefinitions occurs then the value returned by 'foo()'
36  * method must be different from one returned previous invocation.
37  * The test passes if method 'foo()' of the RedefinedClass returns expected
38  * values.
39  * The test consists of three program:
40  *   redefine001.java - launches jdb and debuggee, writes commands to jdb, reads the jdb output,
41  *   redefine001a.java - the debugged application.
42  *   RedefinedClass.java - the class to be redefined.
43  *   newclass_g/RedefinedClass.java - the redefining class.
