 * @test
 *
 * @summary converted from VM Testbase nsk/jdb/print/print002.
 * VM Testbase keywords: [quick, jpda, jdb]
 * VM Testbase readme:
 * DECSRIPTION
 * This is a test for the 'print <expr>' command.
 * The test checks if jdb correctly prints values for the following
 * expressions:
 *  - arithmetic expression of local variables,
 *  - boolean expression of local variables,
 *  - string field deeply nested in class hierarchy.
 * The test passes when all printed values are equal to expected ones.
 * The test consists of two program:
 *   print002.java - launches jdb and debuggee, writes commands to jdb, reads the jdb output,
 *   print002a.java - the debugged application.
 * COMMENTS
 * The test replaces the nsk/jdb/print/print001 one.
 * Test was fixed according to test bug:
 *     4862693 NSK testcase nsk/jdb/print/print002 fails with operation not yet supported
 *
 * @library /vmTestbase
 *          /test/lib
 * @run driver jdk.test.lib.FileInstaller . .
