title: jrebel cause error in hybris when starting with debug mode
body: <p>I already set up some hybris projects and used jrebel in them, but this project is kind of different.</p>
  
  <p>When I run my server with <code>./hybrisserver.sh debug</code> and <code>tomcat.debugjavaoptions=-Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,server=y,address=8000,suspend=n</code>, it starts correctly and I can debug the server.</p>
  
  <p>When I run my server with <code>./hybrisserver.sh debug</code> and <code>tomcat.debugjavaoptions=-Xdebug -Xnoagent -Xrunjdwp:transport=dt_socket,server=y,address=8000,suspend=n -agentpath:%JREBEL_HOME%/lib/libjrebel64.dylib</code>, it doesn't start and I get the following error.</p>
  
  <p>When I run my server with <code>./hybrisserver.sh</code> and <code>tomcat.javaoptions=-agentpath:%JREBEL_HOME%/lib/libjrebel64.dylib</code> (not the debug options!), it starts normally and jrebel is present in the log.</p>
