/*
 * @test
 *
 * @summary converted from VM Testbase nsk/jdb/dump/dump002.
 * VM Testbase keywords: [quick, jpda, jdb]
 * VM Testbase readme:
 * DESCRIPTION
 *  This is a test for the 'dump' command.
 *  The test works as follows. Upon the debuggee is suspended
 *  on breakpoint, jdb issues 'dump' command for an object
 *  of debugged class and for element in array fields.
 *  The test passes if all checked fields with their values
 *  are listed.
 *  The test consists of two parts:
 *    dump002.java  - test driver, i.e. launches jdb and debuggee,
 *                       writes commands to jdb, reads the jdb output,
 *    dump002a.java - the debugged application.
 * COMMENTS
 *  The test replaces the nsk/jdb/dump/dump001 one.
 *  Test fixed according to test bug:
 *  5045859 TEST_BUG: some JDB tests do not recognize JDB prompt
 *
 * @library /vmTestbase
 *          /test/lib
 * @run driver jdk.test.lib.FileInstaller . .
