Background:
    With latest jre8, when run ca-signed apps that passing bad vmargs/property to vm, the warning dialog is with title "Security Warning" and in more information dialog, it says "Although the application has a digital signature, the application's associated file (JNLP) does not have one......"
    For example, when run the following ca-signed app that trying to pass bad property <property name=javapi.user0" value=testquote /> to vm, a warning dialog with title "Security Warning" will show up.

Steps to reproduce:
    1 Install latest jre8 nightly build#728
    2) Make sure your system/browser can access to internet or disable ocsp/crl check from JCP
    3) Load app javaws http://sqeweb.us.oracle.com/net/sqenfs-1/export1/comp/jsn/users/crystal/DO_NOT_REMOVE_ME/jrebug/vmargs/jnlp/testpropertyquote.jnlp
       It try to pass bad property <property name=javapi.user0" value=testquote /> to vm
       The JNLP file is not signed and only jar file is signed.
    4) If a security warning dialog with title "Security Warning" shows up and in more info dialog it says "Although the application has a digital signature, the application's associated file (JNLP) does not have one......", then this issue is reproduced. See attached security-warning.png and security-warning-moreinfo.png.

But for apps that pass valid property to vm, the title of warning dialog is "Security Information".

Steps to reproduce:
    1) Install latest jre8 nightly build#728
    2) Make sure your system/browser can access to internet or disable ocsp/crl check from JCP
    3) Load app javaws http://sqeweb.us.oracle.com/net/sqenfs-1/export1/comp/jsn/users/crystal/DO_NOT_REMOVE_ME/jrebug/vmargs/jnlp/testpropertyTest1.jnlp
       It try to pass valid property <property name="http.keepAlive" value="VALUE"/> to vm
       The JNLP file is also not signed and only jar file is signed.
    4) A security warning dialog with title "Security Information" will show up. See attached security-info.png
