itw-settings: which jars need to be appended to the bootclasspath

[Treutwein Bernhard]

Trying to  use netx.jar under MS Windows for starting the itw-settings GUI, I was able to start the
GUI with the following (minimal) script itw-settings.cmd:

   set JAVA=java.exe
   set ITW_Home=H:/Java
   set NetX=netx.jar
   start %JAVA% -Xbootclasspath/a:%ITW_Home%/%NetX%  net.sourceforge.jnlp.controlpanel.ControlPanel

the bash script for Linux has some other jars appended to the bootclasspath:
	plugin.jar, jsobject.jar, tagsoup.jar, and rhino.jar

Since I left these out in my -Xbootclasspath/a: option, what errors should I expect? 
Until now I did not see any errors, except that the extended policy editor tries to find
the policy file in the wrong location.

I am currently trying this in Windows 7 with the Oracle JRE 1.8.0_181 as future substitute for javaws.
The netx .jar was built under Debian 9.5 (stretch) from the icedtea-web-1.7.1 sources.

Experimenting with the prebuild msi installer from the ojdkbuild (https://github.com/ojdkbuild/ojdkbuild) 
under Windows 10 I had to replace netx.jar by javaws.jar and to use subst J: <java-install-drive-path>
since the default installation path contains a blank ("Program Files").

Regards & thanks in advance
