* @summary converted from VM Testbase nsk/jdb/unwatch/unwatch002.
* VM Testbase keywords: [jpda, jdb]
* VM Testbase readme:
* DECSRIPTION
* A positive test case for the 'unwatch all <class id>.<field name>' command.
* There are two test cases:
* - unwatch all for the fields defined in class,
* - unwatch all for the fields defined in inner class.
* At first phase of testing the full watch is set for all checked fields with
* "watch all" command. Then debugged application invokes the methods (updateFields)
* in which all checked fields participate in assigned expressions as well as are
* assigned to. Thus the jdb should report the access event and modification event
* for the fields.
* At seconds phase of testing all watch monitors are deleted with the tested
* command. Then updateFields methods are invoked in debuggee again.
* The test passes jdb reports only once an access and modification events for
* every checked fields. Correct report message in jdb stdout should contain full
* name of the field and "access encountered" or "will be" words.
* The test consists of two program:
* watch002.java - launches jdb and debuggee, writes commands to jdb, reads the jdb output,
* watch002a.java - the debugged application.
* COMMENTS
