> Key: GEODE-6562
> URL: https://issues.apache.org/jira/browse/GEODE-6562
> Project: Geode
> Issue Type: Bug
> Components: core
> Reporter: Kirk Lund
> Assignee: Dan Smith
> Priority: Major
>
> This is observable with MultipleCacheJUnitTest:
> {noformat}
> 1: @Before
> 2: public void startLocator() throws IOException {
> 3: InternalDistributedSystem.ALLOW_MULTIPLE_SYSTEMS = true;
> 4: locator = Locator.startLocatorAndDS(0, locatorFolder.newFile("locator.log"), null);
> 5: props = new Properties();
> 6: props.setProperty(ConfigurationProperties.LOCATORS, "locahost[" + locator.getPort() + "]");
> 7: }
> {noformat}
> InternalLocator.startDistributedSystem() creates a DS connection and then passes it to startCache:
> {noformat}
> 597: private void startDistributedSystem() throws UnknownHostException {
> ...
> 648: this.myDs = (InternalDistributedSystem) DistributedSystem.connect(connectEnv);
> ...
> 661: startCache(myDs);
> {noformat}
> But then InternalLocator.startCache(DistributedSystem) creates a new Cache without using the DistributedSystem passed in (it only uses its properties):
> {noformat}
> 670: private void startCache(DistributedSystem ds) {
> ...
> 674: this.myCache = (InternalCache) new CacheFactory(ds.getProperties()).create();
> {noformat}
> Because of the way that CacheFactory was implemented to support ALLOW_MULTIPLE_SYSTEMS, it always creates a new instance of DistributedSystem. That old behavior was carried forward to the new InternalCacheBuilder.
