Description

When running a command directly from the cli using bin/shell, this triggers a null pointer exception.

I.e, in a terminal, run the following:

{install_dir}/bin/shell echo hello

You will receive this stacktrace:

Exception in thread "main" java.lang.NullPointerException: "in" is null!
