           Summary: Unresolved OSGi requirement breaks Eclipse help system
           Product: Fedora
           Version: rawhide
         Component: jetty

Description of problem:

When using the integrated Eclipse help system, I see this error in the log:

!ENTRY org.eclipse.ui 4 0 2017-02-27 14:19:57.069
!MESSAGE Unhandled event loop exception

Looking at the OSGi console, I see the following unresolved bundles:

g! ss -s INSTALLED
id      State       Bundle
97      INSTALLED   org.eclipse.equinox.http.jetty_3.3.0.v20170227-1124
143     INSTALLED   org.eclipse.jetty.http_9.4.2.v20170220
145     INSTALLED   org.eclipse.jetty.security_9.4.2.v20170220
146     INSTALLED   org.eclipse.jetty.server_9.4.2.v20170220
147     INSTALLED   org.eclipse.jetty.servlet_9.4.2.v20170220

And it seems to be caused by a missing capability:

g! diag 143
org.eclipse.jetty.http [143]
  Unresolved requirement: Require-Capability: osgi.extender;
filter:="(osgi.extender=osgi.serviceloader.processor)"

This requirement seems to be new in:

jetty-http-9.4.2-1.v20170220.fc26.noarch

It doesn't look like there is a provider of this capability in Fedora. Any idea
if this requirement can be made optional?
