@prabhjyotsingh I left one minor comment. Besides that I found 1 other
issues.
* Code duplication and inconsistency between `ShellInterpreter` and
`ShellSecurityImpl`. Both of these 2 classes will create DefaultExecutor and do
the real shell execution. But it seems the command in `ShellSecurityImpl` can
not be canceled, because it is not put in `executors`. It would be better to
put the common logic together.
But this issue is not related with this ticket, could be done in another
ticket.
