Description

After upgrading from Flink 1.2.0 to 1.2.1 I got the following error
```
07:54:52,395 ERROR org.apache.flink.api.common.io.DelimitedInputFormat - Unexpected problen while getting the file statistics for file 'mytestfile': -1
java.lang.ArrayIndexOutOfBoundsException: -1

I have created a test repo to isolate the issue here

and reproduced the bug using travis
