A DESCRIPTION OF THE PROBLEM :
The full description of the java.io.ObjectOutputStream.reset() method says

    Objects previously written to the stream will not be refered to as already being in the stream.

That word is spelled "referred".

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
Objects previously written to the stream will not be referred to as already being in the stream.
ACTUAL -
Objects previously written to the stream will not be refered to as already being in the stream.

Yep, minor typo.
