Yes :-(
For the NPE:
Recorded as JENA-1791 and proposal to fix in PR#643
the --data seems to be a different issue to be investigated.

An example in my book "Learning SPARQL" suggests the following command

arq --query ex007.rq
This worked fine as shown with Jena 3.10.0 build date
2018-12-30T15:45:57+0000 but got the Exception shown below with 3.13.1
build date 2019-10-06T18:57:39+0000. When I add --data ex002.ttl to that
command line, I don't get the Exception, but it doesn't return any
results either.
Thanks,
