Docker Logs weird behaviour

[Khazrak]

When reading logs it seems like the first line is missing and some weird characters appear at the start of every line (if casting it to int I get the value 1).

My college also said that his last line is missing. My mongodb example does not illustrate that, will try to find a good example.

I attached how the logs looks with "docker logs" and how it looks with Java:
DockerLogs.txt

I tried using charsets of UTF-8 and US-ASCII to see if that helped but same result

It seems that some pieces of the header are also displayed. Will have a look.

Now the headers works fine and the first line displays.
But it doesn't show all the lines in the end, they get suspiciously cut (attached log):
DockerLogsCut.txt

[Khazrak]

It now gets all the logs :)

The only thing to remark is that I get this logged every time at the start:

[pool-1-thread-1] ERROR java.io.InputStreamReader - Error while pumping stream.

Will look at fixing that too then :) So close!

Can you share a way to repro? Can't seem to hit it myself.

LogProblem.txt

A class with a big junit test that get the problem.

Specs:
Running on Ubuntu 16.04 and using docker version 1.11.2 (I know, the lib is for 1.9.1, but there is no difference in log api that I've found)
