 *
 * @summary converted from VM Testbase nsk/jdb/untrace/untrace001.
 * VM Testbase keywords: [jpda, jdb]
 * VM Testbase readme:
 * DECSRIPTION
 * A positive test case for the 'untrace methods <thread id>' command.
 * The debuggee program (untrace001a.java) creates an additional
 * thread with name like "MyThread-1" and starts it. The jdb
 * suspends the debuggee at a moment when the additional thread is
 * waiting for notification for lock objects and then turns on method
 * tracing for this thread by 'trace methods <thread id>' command.
 * After expected notification the additional thread invokes checked
 * debuggee's methods. Thus jdb output must have the trace messages of checked methods'
 * entrance and exit.
 * At second phase jdb suspends the debuggee and turns off tracing
 * by checked command. After resuming the debuggee's additional
 * thread invokes checked methods again. Tracing messages and debuggee's
 * suspentions are not expected at this moment.
 * The test passes if jdb output has one 'enter' messages and one 'exit'
 * messages for every checked method.
 * The test consists of two program:
 *   untrace001.java - launches jdb and debuggee, writes commands to jdb, reads the jdb output,
 *   untrace001a.java - the debugged application.
 * COMMENTS
 * Modified due to fix of the bug:
 *  4785781 TTY: debuggee hangs in jdb 'untrace001' test in Mantis
