title: Can't start Liberty server in debug mode - "agent library failed to init: jdwp"
body: <p>When I try to start a WebSphere Liberty server in <em>debug</em> mode (to connect the Eclipse Java debugger) via:</p>
  
  <p><code>$ ./wlp/bin/server debug MyServer</code></p>
  
  <p>I get the following error:</p>
  
  <pre><code>Error occurred during initialization of VM
  agent library failed to init: jdwp
  ERROR: Cannot load this JVM TI agent twice, check your java command line for duplicate jdwp options.
  </code></pre>
  
  <p>and the server doesn't start. </p>
