A DESCRIPTION OF THE PROBLEM :
procedure to show this problem:

1. uninstall all jdk/jre
2. install jdk1.4.2_12
3. install jdk1.8.0_45
4. delete %HOME%\AppData\LocalLow\Sun\Java\Deployment folder if exists
5. start some JWS application
6. application doesn't start.

the point is, if %HOME%\AppData\LocalLow\Sun\Java\Deployment\deployment.properties file doesn't exists, javaws (jp2launcher) launch the following process:

"C:\Program Files\Java\j2re1.4.2_12\bin\javaw.exe" -classpath "C:\Program Files\Java\jre1.8.0_45\lib\deploy.jar" com.sun.deploy.panel.JreLocator

This results in blocking to launch the JWS application.

Killing this process and once deployment.properties file created, this problem won't happen again.
