It is thrown by org.csstudio.security.ui.internal.SecurityVariables (C:\eclipse-ibex-v3.1\workspace\.metadata\.plugins\org.eclipse.pde.core\.bundle_pool\plugins). During the call on line 43 because SecuritySupport.getAuthorizations() is null. I suspect there is something wrong in the setup. The authentication (set in product plugin_customisation.ini) is meant to be file at org.csstudio.platform.jaasAuthentication/authorization_file_name=platform:/plugin/org.csstudio.security/authorization.conf but there is no file there Adding this does not change the issue; although I am unsure what the file should contain.
