CMS lazy sweeping

[Michał Warecki]

Hi All,

I'm trying to understand the mark-sweep algorithm. Before I dive into
implementation of CMS in OpenJDK I want to ask a few questions.
Does CMS in OpenJDK use lazy sweeping with a block structured heap? If no,
why? If yes, each block should contain information about class name of
objects allocated in each block.
Furthermore, object header does not have to contain class name because it
is in block header. I think this solution will improve number of cache hits
and heap size.
Are there any information about this?

Thanks,
MW
