|
|
* 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.
