 * @summary JDB problem running monitor command
 * VM Testbase keywords: [jpda, jdb]
 * VM Testbase readme:
 * DESCRIPTION
 * Make sure 'monitor unmonitor 1' does not cause ConcurrentModificationException
 * in the debugger.
 * The jdb sets up line breakpoint at the debugged application. Then one command
 * 'monitor unmonitor 1' is set. After resuming the debuggee stops at the breakpoint.
 * The test passes if correct reply for "unmonitor 1" commanda is found in jdb stdout
 * stream.
 * The test consists of two program:
 *   monitor002.java - launches jdb and debuggee, writes commands to jdb, reads the jdb output,
 *   monitor002a.java - the debugged application.
 *
 * @library /vmTestbase
 *          /test/lib
 * @run driver jdk.test.lib.FileInstaller . .
 * @build nsk.jdb.monitor.monitor002.monitor002
 *        nsk.jdb.monitor.monitor002.monitor002a
 * @run main/othervm PropertyResolvingWrapper nsk.jdb.monitor.monitor002.monitor002
