title: Breakpoints/Frames not working in IntelliJ
body: <p>Hello hoping someone can help me with this.  I have a Spring Maven java Rest project I am running in IntelliJ, I just upgraded to the latest version 2016.1.  JDK version I am using is 1.7.0_79, Maven v4.0 and I have a Tomcat 7 server.  When running the Tomcat server from IntelliJ the debug breakpoints are not catching at all, and I am not seeing any frames.  I have tried everything under the sun to try to resolve this, it used to be working but stopped a few days ago.  The tomcat starts in both debug, and normal mode with no issue... just does not catch the breakpoints.  This is what I have tried</p>
  
  <ol>
  <li><p>Deleted the entire local git branch and recloned in different location and reopened in Intellij.</p></li>
  <li><p>File -> Invalidate Caches/Restart</p></li>
  <li><p>Manually deleting all tomcat server folders and recreating.</p></li>
  <li><p>Switching the debug configuration, to Shared Memory from Socket and vice versa.  </p></li>
  <li><p>Checked for port conflicts for the socket port..</p></li>
  <li><p>I have no method level or exception level breakpoints.</p></li>
  </ol>
  
  <p>If someone could help me develop a step-by-step approach to troubleshooting this that would be great.</p>
