Thanks, the current eclipse-equinox-osgi package works as OGSi 5
dependency, but unfortunately it does NOT work as OSGi 4 dependency.
Building fails with some Java errors when I use the current equinox
package (which provides org.eclipse.osgi_3.9.1.v20131014-1715.jar).

I didn't see that Equinox satisfies the OSGi 5 part, since I didn't use
this package anymore, as soon I recognized that NetBeans does not build
with it.
