Grizzly and EOFException

Occasionally, maybe once every week or so, I will get an EOFException from
Grizzly Server when using Jersey. Is this to be expected or something I
need to look into?

They look like this:

java.io.EOFException: null

Hi Robert,

do you see any functional problem related to this issue or it's just
logging?
It looks like a client unexpectedly closes the connection at the time we
try to read more data.

WBR,
Alexey.

Really hard to say, they are all IOS clients. But I have not heard any
complaints. Thanks for the explanation!
