There was a problem hiding this comment.
To make the *WorksCorrectlyWithoutConflicts() tests more deterministic, since the bug occurs when calling a custom procedure/function during the refresh phase.
With a high refreshTime the tests are almost always green even without the synchronized clauses.

Steps to reproduce
Create multiple procs/overrides with low refresh config value (e.g.:
apoc.custom.procedures.refresh=10)Why
Sometimes it can happen that during the refresh the system database has discrepancies with the cache (i.e.
registeredProcedureSignaturesandregisteredUserFunctionSignatures) and therefore some procedures/functions are mistakenly de-registered.synchronizedinrestoreProceduresAndFunctions,storeFunctionandstoreProceduremethods
