> When using a JDBC message store, if the housekeeping task is triggered while the DB connection
is lost (DB down or network problem) then the Broker dies with the stack below.
> This happens when a message expires and the housekeeping task tries to delete it from
the store while the DB is not accessible. In this case a StoreException is thrown but this
exception is not catched by the Housekeeping task which is only catching ConnectionScopedRuntimeExceptions.
