EnumValidator.validateParameter should check toStringMap first to reduce the times of IllegalArgumentException creation ----------------------------------------------------------------------------------------------------------------------- Key: WFCORE-3531 URL: https://issues.jboss.org/browse/WFCORE-3531 Project: WildFly Core Issue Type: Bug Components: Domain Management, JMX Environment: JBoss EAP 6.4.16,6.4.18 Reporter: Lin Gao Assignee: Lin Gao Labels: downstream_dependency, performace Original Estimate: 2 days Remaining Estimate: 2 days {panel:title=Description of downstream issue} 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} ---- {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. {panel}
