title: Btrace not returning Anything
body: <p>So I am introducing myself to btrace but currently I am getting no output out of it. With this script :</p>
  
  <p>package com.sun.btrace.samples;</p>
  
  <pre><code>import com.sun.btrace.annotations.*;
  import static com.sun.btrace.BTraceUtils.*;
  
  @BTrace
  public class AllLines {
  @OnMethod(
      clazz="/.*/",
      location=@Location(value=Kind.LINE, line=-1)
  )
  public static void online(@ProbeClassName String pcn, @ProbeMethodName String pmn, int line) {
      print(Strings.strcat(pcn, "."));
      print(Strings.strcat(pmn, ":"));
      println(line);
   } 
  }
  </code></pre>
  
  <p>This come straight from the samples directory, just changed the "clazz="/.*/"," out of desperation to get something printed out. No luck.</p>
  
  <p>The pid I am  pointing btrace at is a simple java program I developped just for testing purpose which calls a certain method on a loop. I am running it through Eclipse.</p>
  
  <p>Any ideas what i could be missing ?
  Thanks!</p>
  
  <p>Update: Turned on debug mode to find out it is hanging at "debug: checking port availability: 2020 ". Any ideas ?</p>
