NPE in EUM Point builder
I get this NPE in the EUM point builder:
Started with Petclinic app and activated EUM with all modules.
The issue could occur due to two potential root causes:
a) Data has been added concurrently to the caching parent point builder, which is not supported atm. This is fixed by adding a critical section.
b) A data point has just been evicted from the cache while at the same time his session info arrived. This is fixed by an additional null check.
