The Generic transport is having problems with Java 9.

This problem can be bypassed with this fix: https://github.com/esa/CCSDS_MO_TRANS/pull/44

However, we will need to address the actual marshalling/unmarshalling of objects using Java 9 in a different fix!

I guess the longer term approach for this specific problem is to remove the inbuilt XML support and have proper MAL XML encoding support.

Fixed with #44 merge.

Note to myself - I will dig up the MAL XML implementation prototype we have and proceed towards open-sourcing and then merging it. The major issue we had with it was failing MAL-MAL Testbed. We still lack the manpower to really debug it, though.
