------------------------------------------
Hi Sam,
Thanks for your report.
This is going to be either a lot of work or a lot less ;-) depending on what
users need...
(1) We should address this in the work-in-progress version 5 to make sure we
get it right there.
(2) Then decide which old 4.x.y branch to backport to if any.
(3) Which branches do you see this being needed: 4.0, 4.1, 4.2, 4.3, 4.4,
and/or 4.5?
(4) Releasing a new version of 4.2.x for example would not fix existing jars,
then what?
Please opine.

> Using Apache Http Client and Core in OSGi environments can fail if multiple
> versions are present, which is common (for example, Eclipse Mars includes
> Http versions 4.3.x, but many popular Eclipse plugins may include 4.2.x). The
> problem is that the dependency from the Http Client OSGi bundle to the Http
> Core OSGi bundle does not specify an upper bound, e.g. Cient 4.2.6 depends on
> Core 4.2.5 *or later.* This can cause Client 4.2.5 to use Core 4.3 which
> completely breaks any plugin that specifies tight version constraints on
> Client 4.2.6 and Core 4.2.5. See
> https://bugs.eclipse.org/bugs/show_bug.cgi?id=492042 for more details.
> When creating OSGi bundles, please specify exact version constraints in the
> manifest, e.g. Import-Package: org.apache.http;version="[4.2.5,4.2.6)",
