2004-07-11  Dalibor Topic  <[EMAIL PROTECTED]>

        * libraries/javalib/java/io/FilePermission.java:
        Resynced with GNU Classpath.

        2004-06-25  Mark Wielaard  <[EMAIL PROTECTED]>

        * java/io/FilePermission.java (usingPerms): Removed.
        (actionsString): Made final.
        (cachePerms): Renamed to checkPerms.
        (checkPerms): Renamed from cachePerms. Call trim() and toLowerCase()
        on action String.
        (FilePermission): Check arguments, call checkPerms().
        (equals): Remove cachePerms() call.
        (implies): Likewise.
