[GSS](7.4.0) CLI accept invalid values for -Xms and -Xmx while adding

The customer has opened one case where they are saying, CLI is not throwing an error while adding invalid values of -Xmx and -Xms.

 

I tried to replicate the same in EAP 7.2.8 and I observe the same behavior.

~~~

[domain@localhost:9990 /] /server-group=main-server-group/jvm=default:write-attribute(name=heap-size,value=toto)

{ "outcome" => "success",

"result" => undefined,

"server-groups" => {"main-server-group" => {"host" => {"master" => { "server-one" => {"response" => { "outcome" => "success", "response-headers" =>

{ "operation-requires-restart" => true, "process-state" => "restart-required" } }}, "server-two" => {"response" => { "outcome" => "success", "response-headers" => { "operation-requires-restart" => true, "process-state" => "restart-required" }

}} }}}} }

~~~

 

However, the server failed to start but it should not accept invalid values likes STRING while addition.
