Cut the number of java.util.RegularEnumSet used for attribute and operation flags and ModelTypeValidators --------------------------------------------------------------------------------------------------------- Key: WFCORE-2927 URL: https://issues.jboss.org/browse/WFCORE-2927 Project: WildFly Core Issue Type: Enhancement Components: Domain Management Reporter: Brian Stansberry Assignee: Brian Stansberry A heap dump of full wildfly standalone-full-ha shows > 14K enum sets with retained heap of over 566K. The bulk of these are for attribute or operation definitions or instances of ModelTypeValidator. The vast majority of these contain the same few combinations of elements, so AD / OD / ModelTypeValidator should detect and use a single instance of these.
