#1853 It has to do with this issue because packageName should not exist. Instead invoker-package should be used (as far as I understand the documentation)
#1302 exactly this issue but only reported for the client

I've just seen this issue, and I've already submitted a patch for the client part: #2016 I will have a look at the server part soon...

[svenpanne]

Fix for server part in #2041.

Oh, thank you. I finally thought about this issue again and wanted to create a pull request. I assume I will wait until that patch is applied which happened already on 2019-02-08
