 * @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

 *      -arch=${os.family}-${os.simpleArch}

 *      -waittime=5

 *      -debugee.vmkind=java

 *      -transport.address=dynamic

 *      -jdb=${test.jdk}/bin/jdb

 *      -java.options="${test.vm.opts} ${test.java.opts}"
