Motivation

Compare the namespace offload policy, the topic offload policy command line update function use int and long type to accept param and miss some param check method, which will cause the param value set as 0 if the param is missed.

Modifications

2. Set a default value if the param is not set, and will check if is default value in PersistentTopicsBase.
3. NamespacesBase and some check.
