    Description

      Setting optional="true" on a deployment module dependency in jboss-deployment-structure.xml is ignored. Allthough the dependency is declared as optional the dependent WAR fails when the optional dependency isn't present.

      The issue is not limited to subdeployment dependencyies (as described in AS7-2832) or additional dependencies (as described in https://community.jboss.org/message/646012). Even the simple form of optional dependency inclusion fails for deployment modules:

      <jboss-deployment-structure>
  <deployment>
    <dependencies>
      <module name="org.apache.log4j" />
      <module name="deployment.not-yet-existing.jar" optional="true" />
    </dependencies>
  </deployment>
</jboss-deployment-structure>

          Bug - A problem that impairs or prevents the functions of the product. AS7-2832 subdeployment dependency to a module with optional="true" leads to a deployment failure when the dependency not available

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
