Description

Calling ParsingReader.read on an "empty" reader throws an exception:

org.apache.tika.exception.ZeroByteFileException: InputStream must have > 0 bytes

However, according to the Reader documentation:

Returns:
The number of characters read, or -1 if the end of the stream has been reached

So this method should return a -1 instead.
