What changes were proposed in this pull request?
This PR change is to reduce creation of too many local hashmap and other objects on repeated processing of OM events during delta sync of Recon with OM.
Some OM background tasks need code optimisations where the process method is creating static maps and other objects again and again with every run which are not needed, so that memory and GC overhead can be reduced.
