Hi,when I use btrace in debug mode,I met some errors

client:

btrace DEBUG: waiting for clients

Here is my script

package com.sun.btrace.samples;
import com.sun.btrace.BTraceUtils;
import com.sun.btrace.annotations.*;
import static com.sun.btrace.BTraceUtils.*;
import com.perfma.loadcontroller.model.Machine;
/*
 * This BTrace script inserts a probe into
 * method entry of java.lang.Thread.start() method.
 * At each Thread.start(), it raises a DTrace probe
 * in addition to printing the name of the thread.
 * A D-script like jthread.d may be used to get the
 * associated DTrace probe events.
 */
@BTrace public class ThreadStart {
    @OnMethod(
        clazz="com.perfma.loadcontroller.core.service.impl.MachineServiceImpl",
        method="heartbeat",
location = @Location(Kind.ENTRY)
    )
    public static void onnewThread(@Self Object t,Machine m) {
	BTraceUtils.jstack();       
// D.probe("jthreadstart", Threads.name(t));
        //println("starting " + Threads.name(t));
    }
}

And my cmd:

./bin/btrace  -cp ~/xsea/lib/loadcontroller-model-1.1-SNAPSHOT.jar -v 19660 ThreadStart.java

where is the problem?
