Description

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

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