Date Wed, 10 Jan 2007 15:05:27 GMT

     [ https://issues.apache.org/jira/browse/HARMONY-2965?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Chunrong Lai updated HARMONY-2965:
----------------------------------

    Estimated Complexity: Advanced
             Description: 
This patch introduces a new parallel compactor for GCv5. This new parallel compactor has only
three passes during the compaction process. 

This patch has also the code to handle out-of-space issue when mature space can not hold all
the live objects from  nursery space. It will extend mature space and shrink the nursery space.

This patch is built based on Harmony-2945. Since H2945 is not in SVN, this patch is generated
with diff. To apply this patch, please firstly apply H2945, and then enter gc_gen directory
and apply this patch with "patch p1 < patch-file-name".

Thanks.
