selectBooleanCheckbox with ajax is not working on TomEE 8.0.8 - ajax

Question

I have a question concerning JSF/PrimeFaces on TomEE. Running the following code (PrimeFaces 7.0)
<h:selectBooleanCheckbox value="#{dashboardUIController.includeMyself}">
<p:ajax event="change" listener="#{dashboardUIController.onIncludeMyself()}" update="teamVisitedCountriesChart teamTravelsForProjectsChart"/>
</h:selectBooleanCheckbox>
on TomEE version 8.0.6, everything is fine. Running it on TomEE version 8.0.8, it results in the following exception:
java.lang.NullPointerException

It seems that TomEE 8.0.8 includes a Mojarra version, which forbids an ajax inside a selectBooleanCheckBox element.
So, does anybody know the exact root cause of this exception, and also, how to get it running on TomEE 8.0.8?
Thanks!
