Livelock creating lots of cache managers in parallel ---------------------------------------------------- Key: ISPN-1017 URL: https://issues.jboss.org/browse/ISPN-1017 Project: Infinispan Issue Type: Bug Components: Locking and Concurrency Reporter: Dan Berindei Assignee: Dan Berindei While running the HotRod client test suite I sometimes get a livelock and the thread dump shows a lot of stack traces like this: "pool-2-thread-20" prio=10 tid=0x6a63ec00 nid=0x2d71 runnable [0x6943e000] java.lang.Thread.State: RUNNABLE at java.util.HashMap.get(HashMap.java:320) at org.infinispan.factories.ComponentRegistry.isGlobal(ComponentRegistry.java:138) at org.infinispan.factories.ComponentRegistry.registerComponent(ComponentRegistry.java:130) at org.infinispan.factories.AbstractComponentRegistry.registerComponent(AbstractComponentRegistry.java:185) at org.infinispan.factories.AbstractComponentRegistry.getOrCreateComponent(AbstractComponentRegistry.java:326) at org.infinispan.factories.AbstractComponentRegistry.invokeInjectionMethod(AbstractComponentRegistry.java:254) at org.infinispan.factories.AbstractComponentRegistry$Component.injectDependencies(AbstractComponentRegistry.java:843) at org.infinispan.factories.AbstractComponentRegistry.registerComponent(AbstractComponentRegistry.java:228) at org.infinispan.factories.ComponentRegistry.registerComponent(ComponentRegistry.java:133) at org.infinispan.factories.AbstractComponentRegistry.registerComponent(AbstractComponentRegistry.java:185) at org.infinispan.factories.InternalCacheFactory.bootstrap(InternalCacheFactory.java:102) at org.infinispan.factories.InternalCacheFactory.createAndWire(InternalCacheFactory.java:77) at org.infinispan.factories.InternalCacheFactory.createCache(InternalCacheFactory.java:61) at org.infinispan.manager.DefaultCacheManager.createCache(DefaultCacheManager.java:538) at org.infinispan.manager.DefaultCacheManager.getCache(DefaultCacheManager.java:443) at org.infinispan.manager.DefaultCacheManager.getCache(DefaultCacheManager.java:412) at org.infinispan.server.core.AbstractProtocolServer.startDefaultCache(AbstractProtocolServer.scala:108) at org.infinispan.server.core.AbstractProtocolServer.start(AbstractProtocolServer.scala:69) at org.infinispan.server.hotrod.HotRodServer.start(HotRodServer.scala:48) at org.infinispan.server.hotrod.test.HotRodTestingUtil$.startHotRodServer(HotRodTestingUtil.scala:77) at org.infinispan.server.hotrod.test.HotRodTestingUtil$.startHotRodServer(HotRodTestingUtil.scala:57) at org.infinispan.server.hotrod.test.HotRodTestingUtil$.startHotRodServer(HotRodTestingUtil.scala:46) at org.infinispan.server.hotrod.test.HotRodTestingUtil$.startHotRodServer(HotRodTestingUtil.scala:43) at org.infinispan.server.hotrod.test.HotRodTestingUtil$.startHotRodServer(HotRodTestingUtil.scala:37) at org.infinispan.server.hotrod.test.HotRodTestingUtil.startHotRodServer(HotRodTestingUtil.scala) at org.infinispan.client.hotrod.TestHelper.startHotRodServer(TestHelper.java:34) at org.infinispan.client.hotrod.CacheManagerStoppedTest.createCacheManager(CacheManagerStoppedTest.java:31) This seems to be caused by the fact that the componentScopesLookup map is not synchronized and multiple threads write to it at the same time, leaving it in an invalid state. -- This message is automatically generated by JIRA.
