Temporal resource miss on Informer index

[csviri]

Describe the bug

If I add an index to the Informer, and later retrieve resource using byIndex sometimes not the entire set of resources are received. This is caused by the fact that when the informer updates index first it removes the old item later adds it. So when reading the just in time that event is received, it might not return the related item:

I know that it is noted in the Javadoc that this is because it is not fully synchronized, and we probably don't want that since would affect the performance, but maybe we can find a different solution
