Hello. We just updated to 1.11.dev0 and running a jvm run task doesn't work. The error we get is:

Exception caught: (<type 'exceptions.TypeError'>)

Exception message: can only concatenate list (not "NoneType") to list

The root cause seems to be this commit: https://github.com/pantsbuild/pants/commit/71467604c5d43df6000995346f245f3768441c03 The target should default to

[]

(we don't use any extra jvm options) but it seems the

get_field_value

might be run on a wrong target here: https://github.com/pantsbuild/pants/commit/71467604c5d43df6000995346f245f3768441c03#diff-330c9a1c6b6b5df53b8e2eae2f383035R85 I get the required empty list if I change

target.payload....

to

binary.payload...

Is this diagnosis correct?
