[jira] [Created] (VFS-593) duplicated Strings inside WindowsLocalFile

Sam Halliday created VFS-593:
--------------------------------

             Summary: duplicated Strings inside WindowsLocalFile
                 Key: VFS-593
                 URL: https://issues.apache.org/jira/browse/VFS-593
             Project: Commons VFS
          Issue Type: Bug
    Affects Versions: 2.0
            Reporter: Sam Halliday


I did a YourKit analysis of a heapdump when running ENSIME, which uses VFS2, and I found several GB (25%) of the heap was wasted on duplicated strings within VFS2.

This could be averted by using `.intern()` on Strings that represent paths.
