Hi Jacques,

This seems to be a bug in java.util.concurrent related logic. Perhaps you
can provide more context in a Jira to try and tackle it?

Re: NPE in R16 demo

I am just guessing...

ArtifactInfoFactory: it is possible that someone visited the "Artifact
info" page of webtools in the attempt to generate meta-data for the
services/entities/screens... if this is the case it should be possible to
replicate (and it may end up being an error in a service/eca definition or
similar)

Yes this is the context from the stack trace, that's why I posted, I think we can indeed debug it
