When deloyment.webjava.enabled sets to "false", uninstalling jre 8 will leave javaws in system32

*** Tested configuration:
-x86 Windows 7
- jre 8-nightly build#472

*** Steps to reprocue:
0) Remove all jre on the test system
1) Install jre8-nightly (build 472) from
http://rehudson.us.oracle.com:8080/hudson/job/jdk8_deploy-1-prebuild/ws/bundles/windows-i586/
2) Invoke the java control panel and click  "Security" tab
3) Uncheck the box to disable java content in the browser  and save the option
(this will set  deloyment.webjava.enabled=false)
4) Uninstall jre 8 from the system

If javaws.exe remains in /system32 after un-installation, the issue is reproducible.  You can see the javaws error message if executing from the command line
