* @summary converted from VM Testbase nsk/jdb/trace/trace001.
* VM Testbase keywords: [jpda, jdb]
* VM Testbase readme:
* DECSRIPTION
* A positive test case for the 'trace methods <thread id>' command.
* The debuggee program (trace001a.java) creates two of additional
* threads with name like "MyThread-<number>" and starts them. The jdb
* suspends the debuggee at a moment when the additional threads are
* waiting for notification for lock objects and then turns on method
* tracing for these threads by checked command. After expected
* notification the additional threads invoke checked debuggee's methods.
* Thus jdb output must have the trace messages of checked methods'
* entrance and exit. The test passes if jdb output has two 'enter' messages
* and two 'exit' messages for every checked method.
* The test consists of two program:
* trace001.java - launches jdb and debuggee, writes commands to jdb, reads the jdb output,
* trace001a.java - the debugged application.
