Like open-xchange-ajp this new package provides the service open-xchange-httpservice which is required by the open-xchange package. This way open-xchange-ajp and open-xchange-grizzly can both satisfy open-xchange's requirement for the open-xchange-httpservice. Open-xchange-ajp and open-xchange-grizzly block each other so that they can't be installed at the same time.
This package currently includes the bundles com.openxchange.http.grizzly and com.openexchange.http.requestwatcher which extends grizzly with the functionality to log long running requests that might have got stuck during processing.
