> This is an implementation of CDS support code for DRLVM.
> That was developed in Sept 2006. I'm am attaching it as an archive containing the files which were added or modified while implementing the feature. I didn't do any merge with current drlvm sources. I hope the code will be useful to enable CDS feature in the current drlvm.
> The attache code allowed storing of an image of classes into a shared archive and loading the archive at further  vm startups. The list of classes to be stored was read from an external file.
> A the moment I last tried the code, It was able to run EHWA on windows and "Hello world" on linux.
> Performance gain at startup was ~10% on "Hello world" application and 1-2% on Eclipse startup.
