[jboss-jira] [JBoss JIRA] Created: (JBCACHE-1319) NPE with CacheMode.LOCAL and buddy replication enabled

NPE with CacheMode.LOCAL and buddy replication enabled ------------------------------------------------------ Key: JBCACHE-1319 URL: http://jira.jboss.com/jira/browse/JBCACHE-1319 Project: JBoss Cache Issue Type: Bug Security Level: Public (Everyone can see) Affects Versions: 2.1.1.GA Reporter: Brian Stansberry Assigned To: Manik Surtani Priority: Minor Proving the theory no good deed goes unpunished, the fix for JBCACHE-1311 results in an NPE if a cache is configured for local mode but has BR enabled. Minor issue, as this isn't a meaningful config; just cropped up in an AS unit test one of whose permutations by chance used such a config: NPE is from ResponseValdityFilter, which passes a null members list to new ArrayList(Collection): java.lang.NullPointerException at java.util.ArrayList.<init>(ArrayList.java:133) at org.jboss.cache.interceptors.DataGravitatorInterceptor$ResponseValidityFilter.<init>(DataGravitatorInterceptor.java:482) at org.jboss.cache.interceptors.DataGravitatorInterceptor.gravitateData(DataGravitatorInterceptor.java:338) at org.jboss.cache.interceptors.DataGravitatorInterceptor.remoteBackupGet(DataGravitatorInterceptor.java:286) at org.jboss.cache.interceptors.DataGravitatorInterceptor.handleGetMethod(DataGravitatorInterceptor.java:184) at org.jboss.cache.interceptors.DataGravitatorInterceptor.handleGetKeyValueMethod(DataGravitatorInterceptor.java:100) at org.jboss.cache.interceptors.MethodDispacherInterceptor.invoke(MethodDispacherInterceptor.java:84) at org.jboss.cache.interceptors.Interceptor.nextInterceptor(Interceptor.java:111) at org.jboss.cache.interceptors.MethodDispacherInterceptor.invoke(MethodDispacherInterceptor.java:58) at org.jboss.cache.interceptors.Interceptor.nextInterceptor(Interceptor.java:111) at org.jboss.cache.interceptors.CacheLoaderInterceptor.handleGetKeyValueMethod(CacheLoaderInterceptor.java:146) at org.jboss.cache.interceptors.ActivationInterceptor.handleGetKeyValueMethod(ActivationInterceptor.java:118) at org.jboss.cache.interceptors.MethodDispacherInterceptor.invoke(MethodDispacherInterceptor.java:84) at org.jboss.cache.interceptors.Interceptor.nextInterceptor(Interceptor.java:111) at org.jboss.cache.interceptors.PessimisticLockInterceptor.handleGetKeyValueMethod(PessimisticLockInterceptor.java:347) at org.jboss.cache.interceptors.MethodDispacherInterceptor.invoke(MethodDispacherInterceptor.java:84) at org.jboss.cache.interceptors.PessimisticLockInterceptor.invoke(PessimisticLockInterceptor.java:81) at org.jboss.cache.interceptors.Interceptor.nextInterceptor(Interceptor.java:111) at org.jboss.cache.interceptors.MethodDispacherInterceptor.invoke(MethodDispacherInterceptor.java:58) at org.jboss.cache.interceptors.Interceptor.nextInterceptor(Interceptor.java:111) at org.jboss.cache.interceptors.TxInterceptor.handleNonTxMethod(TxInterceptor.java:456) at org.jboss.cache.interceptors.TxInterceptor.handleGetKeyValueMethod(TxInterceptor.java:250) at org.jboss.cache.interceptors.MethodDispacherInterceptor.invoke(MethodDispacherInterceptor.java:84) at org.jboss.cache.interceptors.Interceptor.nextInterceptor(Interceptor.java:111) at org.jboss.cache.interceptors.CacheMgmtInterceptor.handleGetKeyValueMethod(CacheMgmtInterceptor.java:81) at org.jboss.cache.interceptors.MethodDispacherInterceptor.invoke(MethodDispacherInterceptor.java:84) at org.jboss.cache.interceptors.Interceptor.nextInterceptor(Interceptor.java:111) at org.jboss.cache.interceptors.InvocationContextInterceptor.invoke(InvocationContextInterceptor.java:73) at org.jboss.cache.invocation.AbstractInvocationDelegate.invoke(AbstractInvocationDelegate.java:123) at org.jboss.cache.invocation.AbstractInvocationDelegate.invoke(AbstractInvocationDelegate.java:64) at org.jboss.cache.invocation.CacheInvocationDelegate.get(CacheInvocationDelegate.java:387) at org.jboss.web.tomcat.service.session.JBossCacheWrapper.get(JBossCacheWrapper.java:80) at org.jboss.web.tomcat.service.session.JBossCacheService.loadSession(JBossCacheService.java:312) at org.jboss.web.tomcat.service.session.JBossCacheManager.loadSession(JBossCacheManager.java:1189) at org.jboss.web.tomcat.service.session.JBossCacheManager.findSession(JBossCacheManager.java:933) at org.jboss.test.cluster.defaultcfg.simpleweb.test.SessionCountUnitTestCase.createAndUseSession(SessionCountUnitTestCase.java:951) at org.jboss.test.cluster.defaultcfg.simpleweb.test.SessionCountUnitTestCase.standaloneWarRedeployTest(SessionCountUnitTestCase.java:695) at org.jboss.test.cluster.defaultcfg.simpleweb.test.SessionCountUnitTestCase.testStandaloneRestart(SessionCountUnitTestCase.java:673) One fix is to check for null in the ResponseValidityFilter constructor. Probably better is to detect the CacheMode.LOCAL and don't initialize the whole BR subsystem. -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
