Look or an fix uses of OperationContext.restartRequired() that should be using reloadRequired(). There are very few reasons why a full process restart should be needed for a configuration model change to take effect. Typically a full process restart would only be needed for a domain mode server whose JVM configuration settings have been changed in the host model.

Running "git grep restartRequired()" shows the following suspicious uses:
