8u20: No blocked dialog for plugin and javafx apps when no jre matches the rule specified by Admin(DRS with force)

When there is no jre matches the rule specified by Admin, there is a blocked dialog for javaws apps. But no such dialog for plugin applet and javafx apps.

Steps to reproduce:
test scenario: Admin provide a secure version(version="secure") with "force=true" while no secure jre installed on system
1) Install 8u20 nighty build#2550
2) Download http://sqeweb.us.oracle.com/net/sqenfs-1/export1/comp/jsn/users/crystal/DO_NOT_REMOVE_ME/jrebug/LSPJPI/lib/DeploymentRuleSet.jar and then copy it to deployment.system.home/
In this DeploymentRuleSet.jar, we have:
<ruleset version="1.1">
  <rule> <!-- allow run everything -->
     <id location="http://sqeweb.us.oracle.com/"/>
     <action permission="run" version="SECURE" force="true"/>
  </rule>
  <!-- block everything else -->
  <rule>
     <id/>
     <action permission="block" message="we don't want to run anything else"/>
  </rule>
</ruleset>
3) Make sure you can access to internet or disable OCSP and CRL check from JCP
4) Add information "1.8.0_99" to baseline.versions file under {DEPLOY_USER_HOME}/security/ dir to make test jre as old
5) Load applet: http://sqeweb.us.oracle.com/net/sqenfs-1/export1/comp/jsn/users/crystal/DO_NOT_REMOVE_ME/jrebug/LSPJPI/html/UnsignedSandboxJNLP.html
6) If this app get blocked directly without any blocked dialog, then this bug is reproduced. In log, there is NPE:
java.lang.NullPointerException
at sun.plugin2.applet.Plugin2Manager.setParameter(Unknown Source)
at sun.plugin2.main.client.PluginMain.performSSVValidation(Unknown Source)

at sun.plugin2.applet.Plugin2Manager.initAppletAdapter(Unknown Source)
at sun.plugin2.applet.Plugin2Manager$AppletExecutionRunnable.run(Unknown Source)
at java.lang.Thread.run(Unknown Source)

Expected behavior:
There should be a blocked dialog shows up.

Note:
For javaws apps, there is a blocked dialog. See attachment javaws-blocked-dialog.png

6) There will be a "Java Application Blocked dialog" shows up.
