Felix Meschberger commented on JCR-3745:
----------------------------------------

bq. Class yes, final why?=20

What's the use of extending it ? The ObservationManager is the consumer of =
the instance and it can only support what it can support and thus is expose=
d in this base class. If we later see, that extension makes sense we can st=
ill make it non-final. But making a non-final class final is essentially ki=
lling backwards compatibility.

ckrabbit API:=20

> Compared to the JCR method of the same name, this method takes an array o=
f absPath and additional boolean argument:=20
> Only events whose associated parent node is at one of the paths in <code>=
absPaths</code> (or within its subgraph, if <code>isDeep</code> is <code>tr=
ue</code>) will be received.=20

> Additionally, if <code>noExternal</code> is <code>true</code>, then event=
s from external cluster nodes are ignored. Otherwise, they are not ignored.
