I've created an OSGi issue to clarify whether below snippet is supposed
to always work and after discussing this with BJ, that code is bound to
fail as there is no strong reference to the coordination. The spec and
the CT hint that the thread local (or equivalent construct) which holds
the coordination in the implementation must be a weak reference.
Therefore with the example below, no one is holding a strong reference
to the coordination which then allows it to be garbage collected.
