Probably NPE occurs in TopicMerge processing.

Steps to reproduce:

1. Install DITA-OT 2.1.0 from 2.1...develop
2. Move plugins/org.oasis-open.dita.v1_2 to backup directory.
3. Install DITA 1.3 schema from https://github.com/dita-community/org.oasis-open.dita.dita13.doctypes/tree/develop
4. Modify the catalog file. https://lists.oasis-open.org/archives/dita-comment/201507/msg00001.html
5. Run PDF2 or PDF5 (https://github.com/AntennaHouse/pdf5) from oXygen

I've downloaded the sample zip and built with the upcoming 2.3 code.

The NPE no longer occurs with the DITA 1.3 document types that ship natively with DITA-OT 2.2 and 2.3.

The grammar file copies at dita-community were not the official copies; I suspect either they were out of date or otherwise out of sync with the OASIS versions. There is no error from the topic merge process, and the PDF is produced using the PDF2 transform type.
