Implements org.jruby.util.FileResource.openInputStream.

Doc from org.jruby.util.FileResource.openInputStream.

Opens a new input stream to read the contents of a resource and returns it. Note that implementations may be allocating native memory for the stream, so callers need to close this when they are done with it. users of this method should follow the pattern: close the stream where you open it.

Returns:InputStream

Returns a string representation of the object. Satisfying this method's contract implies a non-null result must be returned.

Returns:String
