Recursive update

I recently started getting the following error when creating a new client based on an existing one:

I am occasionally getting the following error:
Caused by:  Recursive update
java.lang.IllegalStateException: Recursive update

I suspect it might be something to do with the cache being modified inside the computeIfAbsent function here.
