#6 exception thrown if lineSeparator occurs before EOF

[Anonymous]

I was attempting to parse a file which, as near as I can tell, contained a lineSeparator on the last line before the file ended. This causes LinePushbackReader to read the line up to the separator, but it doesn't realize that it's reached the end-of-file. Parsing such a file with any simple, valid LineFormat object will fail with an exception similar to this:

org.sadun.text.ffp.FormatOutOfRangeException: Expected type (from position 4 to position10, length 6, type alphanumeric), out of range in line 'null' (4 characters long)
at org.sadun.text.ffp.LineFormat.parse(LineFormat.java:1180)
at org.sadun.text.ffp.FlatFileParser.parse(FlatFileParser.java:400)
...

(SourceForge won't let me attach the file, ~ 300K)

In my opinion the problem lies in FlatFileParser; when it calls readLine() on LinePushbackReader, it doesn't do a check to see if the result is null. Adding a null check fixes the problem. The patch which fixes the issue is attached.
