[wildfly-dev] Accessing system properties in a subsystem

Hi, I have a subsystem that configures itself from system properties. For example: <system-properties> <property name="RecoveryEnvironmentBean.expiryScannerClassNames" value="com.arjuna.ats.internal.arjuna.recovery.ExpiredTransactionStatusManagerScanner com.arjuna.ats.internal.arjuna.recovery.AtomicActionExpiryScanner"/> </system-properties> In earlier revisions of WFLY this worked fine. However I am now seeing that the system property is not set until after my subsystem has started. I can tell this as I have breakpoints on where I process the property. I can see "MSC service thread 1-4" attempting to process the property (which is not set). I do later see messages that suggest the system property is set but at that the later point: 2016-12-12 17:57:48,042 TRACE [org.jboss.as.controller.management-operation] (Controller Boot Thread) Final response for step handler org.jboss.as.server.operations.SystemPropertyAddHandler@784c8c5f handling add in address [("system-property" => "RecoveryEnvironmentBean.expiryScannerClassNames")] is {"outcome" => "success"} 2016-12-12 17:57:48,093 TRACE [org.jboss.as.controller.management-operation] (Controller Boot Thread) Final response for step handler org.jboss.as.controller.ValidateModelStepHandler@87b4493 handling internal-model-validation in address [("system-property" => "RecoveryEnvironmentBean.expiryScannerClassNames")] is {"outcome" => "success"} Does my subsystem need to depend on something to get the old behaviour of being started after system properties are processed? My subsystem is the transaction one and the service is the recovery manager. Thanks! Tom
