>          Issue Type: Enhancement
>          Components: Domain Management, JMX

> 1. Proposed title of this feature request
> Enum is misspelled causing java.lang.IllegalArgumentException 
> 2. Who is the customer behind the request?
> Account: Hamburg Südamerikanische Dampfschifffahrts-Ge, 5651756 
> 3. What is the nature and description of the request?
> Enum is misspelled causing java.lang.IllegalArgumentException 
> 5. How would the customer like to achieve this? (List the functional requirements here)
> In such way, it should not throw Exception and spelled correctly.
> ENUM : "ReadResourceDescriptionHandler.AccessControl.TRIM_DESCRIPTONS"
> Location Where Enum is Used :
> jboss-as-jmx module:
> ./jmx/src/main/java/org/jboss/as/jmx/model/ResourceAccessControlUtil.java
> Code : op.get(ACCESS_CONTROL).set(ReadResourceDescriptionHandler.AccessControl.TRIM_DESCRIPTONS.toModelNode());
> it's a general internal jboss issue for all queries that somehow involve the JMX related ResourceAccessControlUtil.
> Stacktrace Attached.

> ----
> {panel:title=Description}
> +EnumValidator.validateParameter+ is now trying to call +Enum.valueOf()+ first and fall back to +toStringMap.get(tuString)+ on +IllegalArgumentException+.
> However, +toStringMap+ contains necessary Enum values in most cases, so switch the way to get the +enumValue+ can reduce the times of IllegalArgumentException creation. And Exception creation may affect performance.
