Hi, Alongside the DRLVM codebase, here is a contribution from Intel of an OPEN ( Open Pluggable Extensible Interface ) specification for JVM and Classlibrary-VM Interface development.
URL: http://issues.apache.org/jira/browse/HARMONY-459 We hope that this spec will promote modular component oriented development of core pieces eg., the garbage collector, core VM, Just In Time compiler, ClassLibrary-VM Interface etc. That it will provide a framework for developing and interconnecting alternate component implementations through standardized interfaces. The DRLVM codebase does not quite confirm to the OPEN spec at this point, though that is the final intent. The OPEN specification is also an idea, and by no means complete. We need the community's help in giving the final form to this specification, defining the header files that map to the specification, and then in taking the Harmony implementation forward to be OPEN compatible. Thanks, Rana Dasgupta Intel Middleware Development
