 * @test

 * @summary converted from VM Testbase nsk/jdb/set/set001.
 * VM Testbase keywords: [jpda, jdb]
 * VM Testbase readme:
 * DECSRIPTION
 * A positive test for the 'set <lvalue> = <expr>' command.
 * The test checks if jdb correctly sets value for the following
 * fields and variables:
 *  - static field,
 *  - instance field
 * The jdb suspends the debuggee inside the method runIt and then tries
 * to set new values for the fields and variables using checked command.
 * Then the debuggee checks if modified fields/variables have expected
 * values. If not, then special errorMessage variable is appended with
 * the info of wrong values. The test passes when length of errorMessage
 * is equal to 0, and fails otherwise.
 * The test consists of two program:
 *   set001.java - launches jdb and debuggee, writes commands to jdb, reads the jdb output,
 *   set001a.java - the debugged application.
 * COMMENTS
