    28  * @summary JDB problem running monitor command

    29  * VM Testbase keywords: [jpda, jdb]

    30  * VM Testbase readme:

    31  * DESCRIPTION

    32  * Make sure 'monitor unmonitor 1' does not cause ConcurrentModificationException

    33  * in the debugger.

    34  * The jdb sets up line breakpoint at the debugged application. Then one command

    35  * 'monitor unmonitor 1' is set. After resuming the debuggee stops at the breakpoint.

    36  * The test passes if correct reply for "unmonitor 1" commanda is found in jdb stdout

    37  * stream.

    38  * The test consists of two program:

    39  *   monitor002.java - launches jdb and debuggee, writes commands to jdb, reads the jdb output,

    40  *   monitor002a.java - the debugged application.

    41  *

    42  * @library /vmTestbase

    43  *          /test/lib

    44  * @run driver jdk.test.lib.FileInstaller . .

    45  * @build nsk.jdb.monitor.monitor002.monitor002
