FileChangedReloadingStrategy not working for SubnodeConfiguration with a CombinedConfiguration parent

Description

A SubnodeConfiguration that has a CombinedConfiguration as its parent, doesn't "hot" reload properties even if the combined configuration consists of XMLConfigurations that have the FileChangedReloadingStrategy set, the combined configuration has the setForceReloadCheck flag set and the SubnodeConfiguration was obtained by calling configurationAt method and passing in true for the "supportUpdates" flag.

Here's some code that shows the problem where the final assertion will fail.

@Test
public void testSubnodeReadload() throws ConfigurationException { XMLConfiguration xmlConfiguration = new XMLConfiguration("service.xml"); FileChangedReloadingStrategy fileReloadStrategy = new FileChangedReloadingStrategy(); fileReloadStrategy.setRefreshDelay(1000); xmlConfiguration.setReloadingStrategy(fileReloadStrategy); XMLConfiguration config2 = new XMLConfiguration("environment.xml"); FileChangedReloadingStrategy fileReloadStrategy2 = new FileChangedReloadingStrategy(); fileReloadStrategy2.setRefreshDelay(1000); xmlConfiguration.setReloadingStrategy(fileReloadStrategy2); CombinedConfiguration combinedConfig = new CombinedConfiguration(); combinedConfig.setForceReloadCheck(true); combinedConfig.addConfiguration(xmlConfiguration); combinedConfig.addConfiguration(config2); int queue0threads2 = xmlConfiguration.getInt("messaging-new.queue(0).threads"); assert 2 == queue0threads2; //change the value in service.xml to 4 int queue0threads4 = xmlConfiguration.getInt("messaging-new.queue(0).threads"); assert 4 == queue0threads4; SubnodeConfiguration subConfigHier = xmlConfiguration.configurationAt("messaging-new.queue(0)", true); int queue0threadsCombinedSub4 = subConfigHier.getInt("threads"); assert queue0threadsCombinedSub4 == 4; //change the value service.xml to 8 int queue0threadsCombinedSub8 = subConfigHier.getInt("threads"); assert queue0threadsCombinedSub8 == 8; SubnodeConfiguration subNodeConfigParentIsCombinedConfig = combinedConfig.configurationAt("messaging-new.queue(0)", true); int queue0threadsSub8 = subNodeConfigParentIsCombinedConfig.getInt("threads"); assert queue0threadsSub8 == 8; //change the value service.xml file to 16 int queue0threadsSub16 = subNodeConfigParentIsCombinedConfig.getInt("threads"); assert queue0threadsSub16 == 16; //THIS TEST FAILS }
