What is the status for this module on MX9.14?

[Pluggr]

This module needs to be imported into MX8 and exported to load it into MX9, otherwise the import fails.

Is it reliable to use this package for MX9.14?

Update:

I tried loading a JSON array into the non-persistent object, ran into a NullPointerException in Misc.java in 'traverseObject', caused because boolean hasChild is calculated and does not expect null.

Change
boolean hasChild = traversable(child);
To
boolean hasChild; if (child == null){ hasChild = false; } else { hasChild = traversable(child); }
