GT 4.0 Common Runtime Components
The common runtime components provide GT4 web and pre-web services with a set of libraries and tools that allows these services to be platform independent, to build on various abstraction layers (threading, io) and to leverage functionality lower in the web services stack (WSRF, WSN, etc).
These components are architecturally diverse and it is thus hard to identify an overarching theme. Instead a few sub-themes have been identified and elaborated on in the below.
