      Description

      FULL PRODUCT VERSION :
      Using JRE version 1.7.0_25-b16 Java HotSpot(TM) Client VM

      ADDITIONAL OS VERSION INFORMATION :
      Microsoft Windows 7, Microsoft Windows [Version 6.1.7601]


      A DESCRIPTION OF THE PROBLEM :
      I have Using JRE version 1.7.0_25-b16 Java HotSpot(TM) Client VM on Windows 7 PC.

      I have an RMI server running at 10.0.1.136:9500.

      I have a squid proxy server running at 172.17.1.5:3128.

      I am able to get to the RMI server and execute its methods when there is no proxy between the client (a signed java applet) and the server. I know that the RMI server is working and viable.

      I am calling System.setProperty( " http.proxyHost " , " 172.17.1.5 " ); and System.setProperty( " http.proxyPort " , " 3128 " ); in the init method of my signed applet. I type " s " to dump system and deployment properties before trying to do RMI and I see the two values:
      http.proxyHost = 172.17.1.5
      http.proxyPort = 3128

      I have enabled verbose logging for the following RMI properties in the signed applet client:
      System.setProperty( " sun.rmi.client.logCalls " , " true " );
      System.setProperty( " sun.rmi.loader.logLevel " , VERBOSE);
      System.setProperty( " sun.rmi.server.logLevel " , VERBOSE);
      System.setProperty( " sun.rmi.transport.logLevel " , VERBOSE);
      System.setProperty( " sun.rmi.transport.proxy.logLevel " , VERBOSE);
      System.setProperty( " sun.rmi.transport.tcp.logLevel " , VERBOSE);
      System.setProperty( " sun.rmi.dgc.logLevel " , VERBOSE);
      System.setProperty( " sun.rmi.log.debug " , " true " );

      The signed applet is running at IP Address: 172.17.1.100. It is running in Firefox 22.0.

      I have configure squid proxy server to allow tunneling through port 9500.
      I am supplying the " sun.rmi.transport.proxy.eagerHttpFallback " value: System.setProperty( " sun.rmi.transport.proxy.eagerHttpFallback " , " true " );

      Here is the DEBUG information when I try to invoke RMI:
      Detected proxy: Host=172.17.1.5, Port=3128
      Setting http.proxyHost to 172.17.1.5 and http.proxyPort to 3128

      If I use http (e.g., http://10.0.1.136/sdsvnc) to run the applet, RMI works fine. If I use https (e.g., https://10.0.1.136:443/sdsvnc) to run the applet, RMI fails with the stack trace above.

      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Run a server with RMI at port 9500.
      Access RMI server using a signed applet from an https URL.



      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      RMI works.
      ACTUAL -
