    Description

      JDK 1.6 has File APIs like File.getFreeSpace() which should be used instead of spawning a command process for getting the various disk/partition related attributes. This would avoid spikes in memory consumption by tasks when things like LocalDirAllocator is used for creating paths on the filesystem.
