NPE on acquire lock LockManagerImpl.lockAndRecord ------------------------------------------------- Key: ISPN-635 URL: https://jira.jboss.org/browse/ISPN-635 Project: Infinispan Issue Type: Bug Components: Locking and Concurrency Affects Versions: 4.1.0.Final Reporter: Sanne Grinovero Assignee: Galder Zamarreño Fix For: 4.2.0.BETA1 Attachments: ConcurrentCacheStartupTest.java, More_sophisticated_fix_with_lock_per_cache_name.patch, Too_restrictive_fix.patch I've seen this happening only once, still it's quite puzzling. Maybe proper visiblity of the variables is not guaranteed? java.lang.NullPointerException at org.infinispan.util.concurrent.locks.LockManagerImpl.lockAndRecord(LockManagerImpl.java:83) at org.infinispan.container.EntryFactoryImpl.acquireLock(EntryFactoryImpl.java:210) at org.infinispan.container.EntryFactoryImpl.wrapEntryForWriting(EntryFactoryImpl.java:153) at org.infinispan.container.EntryFactoryImpl.wrapEntryForWriting(EntryFactoryImpl.java:106) at org.infinispan.interceptors.LockingInterceptor.visitPutKeyValueCommand(LockingInterceptor.java:197) at org.infinispan.commands.write.PutKeyValueCommand.acceptVisitor(PutKeyValueCommand.java:76) at org.infinispan.interceptors.base.CommandInterceptor.invokeNextInterceptor(CommandInterceptor.java:118) at org.infinispan.interceptors.base.CommandInterceptor.handleDefault(CommandInterceptor.java:132) at org.infinispan.commands.AbstractVisitor.visitPutKeyValueCommand(AbstractVisitor.java:57) at org.infinispan.commands.write.PutKeyValueCommand.acceptVisitor(PutKeyValueCommand.java:76) at org.infinispan.interceptors.base.CommandInterceptor.invokeNextInterceptor(CommandInterceptor.java:118) at org.infinispan.interceptors.TxInterceptor.enlistWriteAndInvokeNext(TxInterceptor.java:183) at org.infinispan.interceptors.TxInterceptor.visitPutKeyValueCommand(TxInterceptor.java:132) at org.infinispan.commands.write.PutKeyValueCommand.acceptVisitor(PutKeyValueCommand.java:76) at org.infinispan.interceptors.base.CommandInterceptor.invokeNextInterceptor(CommandInterceptor.java:118) at org.infinispan.interceptors.CacheMgmtInterceptor.visitPutKeyValueCommand(CacheMgmtInterceptor.java:113) at org.infinispan.commands.write.PutKeyValueCommand.acceptVisitor(PutKeyValueCommand.java:76) at org.infinispan.interceptors.base.CommandInterceptor.invokeNextInterceptor(CommandInterceptor.java:118) at org.infinispan.interceptors.InvocationContextInterceptor.handleAll(InvocationContextInterceptor.java:57) at org.infinispan.interceptors.InvocationContextInterceptor.handleDefault(InvocationContextInterceptor.java:38) at org.infinispan.commands.AbstractVisitor.visitPutKeyValueCommand(AbstractVisitor.java:57) at org.infinispan.commands.write.PutKeyValueCommand.acceptVisitor(PutKeyValueCommand.java:76) at org.infinispan.interceptors.InterceptorChain.invoke(InterceptorChain.java:273) at org.infinispan.CacheDelegate.put(CacheDelegate.java:429) at org.infinispan.CacheSupport.put(CacheSupport.java:28) at com.atlassian.jira.propertyset.PropertySetCache.setObject(PropertySetCache.java:205) at com.atlassian.jira.propertyset.JiraCachingPropertySet.getString(JiraCachingPropertySet.java:647) at com.opensymphony.user.User.getFullName(User.java:86) at com.atlassian.jira.user.util.UserUtilImpl.getDisplayableNameSafely(UserUtilImpl.java:573) at com.atlassian.jira.plugin.profile.ProfileLinkUserFormat.getInitialParams(ProfileLinkUserFormat.java:47) at com.atlassian.jira.plugin.profile.ProfileLinkUserFormat.format(ProfileLinkUserFormat.java:32) at com.atlassian.jira.plugin.profile.DefaultUserFormatManager.formatUser(DefaultUserFormatManager.java:62)
