[equinox-dev] New area in Equinox and vote request






We are starting a new work item in Equinox, "Framework Layering".  The aim of this work is to separate out a fairly general purpose module layer out of the OSGi framework which supports interface sharing by specification version, as defined in OSGi R3, as well as class sharing by implementation version, as supported in Eclipse 3.0. This separation allows for more flexibility in the use scenarios for OSGi framework implementations.  This layering is being discussed in the OSGi Core Platform Expert Group and the intention is to feed the practical experience gained in Equinox into the CPEG work.


The module layer will accommodate both forms of sharing mentioned above as well as some other useful sharing techniques. A key objective is to enable module reachability to be analysed so that class loaders may be automatically wired together in a delegation network so as to prevent certain varieties of class cast exceptions which are common when more than one version of a given class are loaded in a single JVM.


To that end, we have two volunteers to work in this area.  Glyn Normington and Steve Poole.  I am proposing them to the community as Equinox committers.  Since this is a new area of work there really is not an existing body of code on which Glyn and Steve can "prove themselves" in the normal contributor way.  It is however important that they be able to work freely and efficiently in an Equinox branch dedicated to Framework Layering.  


I have worked with Glyn over the past year in this area and trust that his contributions will be both real and significant.  Please join me in voting +1 for making Glyn and Steve committers.
