jstat reports incorrect values for OU for CMS GC

    XMLWordPrintable

    Details

    • Subcomponent:
      gc
    • Resolved In Build:
      b04

      Description

      With CMS GC, at certain points, 'OU' (Old usage) values reported in the jstat output increase first and then drop down. This is wrong because the 'old usage' drops down without any old generation collection.
