      • Configure a SP/IdP configuration as in documentation.
      • Compile and execute the attached HttpSocketRequest.java against the SP app: 
        javac HttpSocketRequest.java
java HttpSocketRequest http://localhost:8080/sp-app/sample.jsp
      • The java just sends a POST with fake saml response but it closes the socket before sending all the data. Besides the data is sent very slow (1s) to make the server reach the future.get line. At this moment a thread should be hung at the future.get line. You can use a jstack to see it. You can execute the java several times to see several hung threads.
