Can not set thread pool max size to -1 (means no limit) in messaging provider settings in web console

When you try in messaging subsystem, for some messaging provider in provider settings, set thread-pool-max-size to -1, you get message invalid numeric value. But -1 is value that means no limit.
Same problem is in both modes.
Through CLI you can set thread-pool-max-size to -1, but after that in web console is zero value in thread-pool-max-size attribute.
