Konrad Windszus commented on SLING-12816:
-----------------------------------------

I am wondering which exceptions are potentially temporary (i.e. the API 
consumer may trigger a retry). From a JCR point of view this is 
https://developer.adobe.com/experience-manager/reference-materials/spec/jsr170/javadocs/jcr-2.0/javax/jcr/InvalidItemStateException.html
 which may succeed after refreshing the resource resolver. If we don't document 
this it is much harder to write robust code against the JCR resource resolver.
