        Description

        ADDITIONAL SYSTEM INFORMATION :
        Dell
        Intel Core i7-6820HQ @2.7Ghz
        Microsoft Windows [Version 6.1.7601] / Windows 7 enterprise SP1
        Java1.8u181 i586
        Java1.8u181 x64

        A DESCRIPTION OF THE PROBLEM :
        Since JDK-8182548, the "arch" can specify 'in order' which jvm archtecture to select.
        Basically i require an x64 VM to run my app using webstart because of memory usage.
        With both 1.8u181 i586 and x64 installed (as per JDK-8182548) on windows 7.
        My JNLP settings were arch="x86_64" and on a separate testrun arch="amd64"
        It never runs 64bit.
        Whith arch="x86_64" the trace file states:

        Log started: Fri, 24 Aug 2018 16:13:28 +0200
        Java Web Start 11.181.2.13
        Using JRE version
         1.8.0_181-b13 Java HotSpot(TM) Client VM
        java.lang.NullPointerException
        at com.sun.jnlp.SingleInstanceServiceImpl.getIDString(Unknown Source)

        at com.sun.javaws.Main$1.run(Unknown Source)
        at java.lang.Thread.run(Unknown Source)

        (with arch="x86" the or omitting the arch attribute, the JVM does start, but in the 32bit VM)

        REGRESSION : Last worked in version 8u181

        STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
        install both 1.8u181 64 and 32 bit
        run jnlp file with one(or multiple) resource sets, where 'arch' is either "x86_64" or "amd64"
        the popup [Java...] appears and dissapears after long.
        The trace file shows it encountered a nullpointer.

        EXPECTED VERSUS ACTUAL BEHAVIOR :
        EXPECTED -
        The application running on a JVM x64
        ACTUAL -
        The launcher terminates with a nullpointer.
