        A DESCRIPTION OF THE PROBLEM :
        With the release of Java 7 update 65 and Java 8 update 11 a bug has been introduced into javaws on windows platforms which is causing our project's unchanged jnlp launch file to trigger the following error:

        Please note the removal of the http.agent property resolves the NPE, but this is a valid property which has been a part of the project's launch file for years.



        REGRESSION. Last worked in version 8u5

        ADDITIONAL REGRESSION INFORMATION:
        java version "1.8.0_05"
        Java(TM) SE Runtime Environment (build 1.8.0_05-b13)
        Java HotSpot(TM) 64-Bit Server VM (build 25.5-b02, mixed mode)

        STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
        Unfortunately, I have been unable to create a small toy demo example of this bug and cannot yet separate the bug from the context of our project; however, it is very easy for anyone to confirm this bug using the following steps.

        1. Launch the following JNLP file (http://bioviz.org/igb/releases/igb-8.1.9/igb.jnlp) using 1.8.0_5 and note there are no problems.
        2. Launch the same file using 1.8.0_11 or 1.7.0_65
        3. Note the error message and stacktrace
        4. Enable console logging to see the additional error message cited above (i.e. Cannot use secure launcher with main class: "-Dhttp.agent=IGB/8.1 (Webstart)" )

        EXPECTED VERSUS ACTUAL BEHAVIOR :
        EXPECTED -
        Result should be a successful launch of our open source genome browsing software.

        From java console:
        Cannot use secure launcher with main class: "-Dhttp.agent=IGB/8.1 (Webstart)"
        #### Java Web Start Error:
        #### null

        REPRODUCIBILITY :
        This bug can be reproduced always.
