Hi all

I'm trying to resolve this issue -- CSS 4.3.x doesn't run its main help from the menu: Help -> Help Contents.
And prints out the following message:

2017-02-26 22:48:06.953 SEVERE [Thread 1] org.csstudio.logging.PluginLogListener (logging) - Unhandled event loop exception

Regularly I use several update sites to add plugins to CSS:
http://download.controlsystemstudio.org/updates/4.3
http://download.eclipse.org/releases/mars
http://download.eclipse.org/eclipse/updates/4.5

CSS build in question is just a product build downloaded from http://controlsystemstudio.org/controlsystemstudio/current.html#

Well, org.eclipse.help.base is available from the update sites but jetty is not and it was not straightforward to find some update site.
Then I've tried update site listed on eclipse web http://download.eclipse.org/jetty/updates/jetty-bundles-9.x/ but there are other not resolved dependencies and I'm not completely sure about the right version of jetty.
So I'd rather to fix the problem in more systematic way and avoid experiments with third-party plugins and update-sites.

Is there a recommended way how to make the main Help of CSS working ?

Thanks,
Tomas
