[ https://issues.jboss.org/browse/WFLY-11810?page=com.atlassian.jira.plugin... ] Jeff Mesnil updated WFLY-11810: ------------------------------- Description: When org.jboss.as.server.deployment.DeploymentPhaseContextImpl#addDeploymentDependency is used, it is expecting the service to be old-API org.jboss.msc.service.Service and use its getValue() method. This needs to be fixed so that using new MSC Service API works too. was: I have no necessary insight regarding to the code but based on the discussion in WFLY-11603 ([comment|https://issues.jboss.org/browse/WFLY-11603?focusedCommentId=13687...]) it is not possible to use 'org.jboss.msc.Service' API to properly install service and deprecated 'org.jboss.msc.service.Service' API has to be used instead. It is necessary to fix the behavior of the new API so when we switch to it, we don't introduce the issue described and fixed in WFLY-11603 again. As it was an intermittent NPE, there is a risk that during the simple switch from deprecated API the introduced issue is not caught right-away but after some time... -- This message was sent by Atlassian Jira (v7.12.1#712002)
