      Description

      Using the following options in 1.4.2_08

      java -server -XX:+UseParNewGC -XX:+UseConcMarkSweepGC -verbose:gc -XX:+PrintGCDetails -XX:+PrintGCTimeStamps -Xloggc:gclogs.txt -XX:+PrintTenuringDistribution

      the customer reported that some info are not redirected to loggc file (e.g: gclogs.txt)

      - all the tenuring age lines:

      Desired survivor size 262144 bytes, new threshold 0 (max 0)

      and changing also -XX:MaxTenuringThreshold=31 -XX:SurvivorRatio=15 also the age lines

      Desired survivor size 1310720 bytes, new threshold 31 (max 31)
      - age 1: 91872 bytes, 91872 total
      - age 2: 9696 bytes, 101568 total
      - age 3: 9768 bytes, 111336 total
      ...

      - the parallel rescan info:

      25364.895: [Rescan (parallel) , 0.1204188 secs]25374.440: [Rescan (parallel) , 0.2273996 secs]25384.150: [Rescan (parallel) , 0.2250920 secs]25394.0.435:...

      The problem of tenuring lines can be reproduced with any testcase on 1.4.2_13.
      The problem of Parallell Rescan lines requires more testing
      .
