(spec) FilePermission constructor missing spec for null and empty String params

Name: smR10189 Date: 11/18/2003



To create FilePermission object two parameters are passed to the constructor.
The first parameter is a path to a file or directory. The second parameter
is a list of requested actions. The spec shows how to specify a path for
directory using special tokens and also it enumerates "possible actions".

But the spec doesn't define an implementation behavior if:
- the first parameter is null or empty string.
- second parameter is null or empty string.
- a list of requested actions contains actions that differ from
  "possible actions" described by the spec.

See, API spec for java.io.FilePermission constructor below:

  public FilePermission(String path, String actions)
    Creates a new FilePermission object with the specified actions. path is the
    pathname of a file or directory, and actions contains a comma-separated
    list of the desired actions granted on the file or directory. Possible
    actions are "read", "write", "execute", and "delete".

    A pathname that ends in "/*" (where "/" is the file separator character,
    File.separatorChar) indicates a directory and all the files contained in
    that directory. A pathname that ends with "/-" indicates a directory and
    (recursively) all files and subdirectories contained in that directory.
    The special pathname "<<ALL FILES>>" matches all files.

    A pathname consisting of a single "*" indicates all the files in the
    current directory, while a pathname consisting of a single "-" indicates
    all the files in the current directory and (recursively) all files and
    subdirectories contained in the current directory.

  Parameters:
    path - the pathname of the file/directory.
    actions - the action string.
