[patch|^OAK-6463-v1.patch] for the same. 

Issue here was that for any property index update PropertyIndexEditor had to initialize NodeBuilder for all IndexStoreStrategy (which are 1 per mount). Now if the index did not had entries for private mount at setup time (when writes to it were allowed) then later this cases issue as on update the editor would try to eagerly initialize the NodeBuilder for :oak:mount-<>-index node even if no updates need to be done under that.

This patch fixes this by using a lazy builder i.e. use Supplier<NodeBuilder> where NodeBuilder is constructed on demand. With this a mount related index node is not created for normal index updates.

[~stillalex] Please review!
