> Currently, it simply emits a warning. Then, when the taskjvm.sh tries to pipe its output
into this directory, it fails with a strange error code like "exit code: 1" which is not intuitive
to ops. Instead it should simply throw an exception at initialization time rather than attempting
to run the task.
