So I finally went ahead and published/released WildFly Common 1.0.0.Alpha1. It contains the following: • Assertions and validations with standard messages (and IDs) for common conditions such as: • Null method parameters • Assertions for holding/not holding monitor objects • Assertions for nullability of values • Exceptions for unreachable code and impossible switch statements • Utilities for reference types that are cleaned in a background thread • Utilities for defining and using selector pattern Selectors (i.e. where you have to locate an object like a service provider from a static context) Here's the info on how to get/use it: • License: ASL 2.0 • JDK: 1.7 or higher • Maven: org.wildfly.common:wildfly-common:1.0.0.Alpha1 • GitHub: https://github.com/wildfly/wildfly-common • JavaDoc: http://wildfly.github.io/wildfly-common/ • JIRA: None at present, just use https://github.com/wildfly/wildfly-common/issues for now and I'll revisit later More info about the project: • http://dmlloyd.github.io/presentations/wildfly-common/index.html -- - DML
