             Project: MINA SSHD
          Issue Type: Bug
    Affects Versions: 1.0.0
         Environment: java version "1.7.0_85"
OpenJDK Runtime Environment (IcedTea 2.6.1) (Gentoo icedtea-7.2.6.1-r1)

            Reporter: Alon Bar-Lev


Try to execute:

$ echo xxxx | ssh -p @PORT@ root@localhost "cat > /none/exist/path/file"

You should get the following exception in 9:10 attempts:

Exception in thread "sshd-shell[855da06]-thread-1" 
java.lang.NullPointerException

java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615)
        at java.lang.Thread.run(Thread.java:745)

I cannot understand how process can be null in this context.
