We are using the following version of MDHT:
> MDHT R2.1 Version
> Binary Release : https://github.com/mdht/mdht-models/releases/tag/20170106

While invoking any "ConsolFactory.eINSTANCE.createXXX.init()" , sporadically got this nullpointer exception. Not able to reproduce everytime though.

Example of calling init()
ProcedureActivityAct2 act = ConsolFactory.eINSTANCE.createProcedureActivityAct2().init();

Error Details:
17:27:47 java.lang.NullPointerException: null

Not being able to reproduce consistently makes this issue problematic to isolate

Looking at the code - best guess is the annotation that is being used to initialize the object does not have a not null map
CDAUtil.init(object, annotation.getDetails().map());

The annotations are supported through the ecore model deployed in the jar

What is the environment you are running ?

We could add a better NPE check but need to be able to reproduce

Thanks Sean for the reply.

The Null checks are all taken care at our end, but the NPE was coming from the library's CDAUtil.init() sporadically for the same criteria/inputs from our end.
It would be great if you can point the Source code.

We are using this release version:
https://github.com/mdht/mdht-models/releases/tag/20170106

We couldn't find source code for org.eclipse.mdht.uml.cda.util package anywhere.
