I'm getting NullPointerException when i'm trying to remove a parent and a child node in the same transaction. The parent is in the cache but the child isn't. It seems like when the parent is removed it tries to remove the child too but the node doesn't exists. Here is the stack trace: Caused by: java.lang.NullPointerException at org.jboss.cache.commands.write.RemoveNodeCommand.recursivelyMarkAsRemoved(RemoveNodeCommand.java:103) at org.jboss.cache.commands.write.RemoveNodeCommand.perform(RemoveNodeCommand.java:80) at org.jboss.cache.interceptors.CallInterceptor.invokeCommand(CallInterceptor.java:108) at org.jboss.cache.interceptors.CallInterceptor.handleAlterCacheMethod(CallInterceptor.java:173) at org.jboss.cache.interceptors.CallInterceptor.visitRemoveNodeCommand(CallInterceptor.java:143) at org.jboss.cache.commands.write.RemoveNodeCommand.acceptVisitor(RemoveNodeCommand.java:125) at org.jboss.cache.interceptors.base.CommandInterceptor.invokeNextInterceptor(CommandInterceptor.java:116) at org.jboss.cache.interceptors.EvictionInterceptor.visitRemoveNodeCommand(EvictionInterceptor.java:223) at org.jboss.cache.commands.write.RemoveNodeCommand.acceptVisitor(RemoveNodeCommand.java:125) at org.jboss.cache.interceptors.base.CommandInterceptor.invokeNextInterceptor(CommandInterceptor.java:116) at org.jboss.cache.interceptors.MVCCLockingInterceptor.handleRemoveNodeCommand(MVCCLockingInterceptor.java:117) at org.jboss.cache.interceptors.base.PrePostProcessingCommandInterceptor.visitRemoveNodeCommand(PrePostProcessingCommandInterceptor.java:126) at org.jboss.cache.commands.write.RemoveNodeCommand.acceptVisitor(RemoveNodeCommand.java:125) at org.jboss.cache.interceptors.base.CommandInterceptor.invokeNextInterceptor(CommandInterceptor.java:116) at org.jboss.cache.interceptors.base.CommandInterceptor.handleDefault(CommandInterceptor.java:131) at org.jboss.cache.commands.AbstractVisitor.visitRemoveNodeCommand(AbstractVisitor.java:75) at org.jboss.cache.commands.write.RemoveNodeCommand.acceptVisitor(RemoveNodeCommand.java:125) at org.jboss.cache.interceptors.base.CommandInterceptor.invokeNextInterceptor(CommandInterceptor.java:116) at org.jboss.cache.interceptors.TxInterceptor.attachGtxAndPassUpChain(TxInterceptor.java:301) at org.jboss.cache.interceptors.TxInterceptor.handleDefault(TxInterceptor.java:283) at org.jboss.cache.commands.AbstractVisitor.visitRemoveNodeCommand(AbstractVisitor.java:75) at org.jboss.cache.commands.write.RemoveNodeCommand.acceptVisitor(RemoveNodeCommand.java:125) at org.jboss.cache.interceptors.base.CommandInterceptor.invokeNextInterceptor(CommandInterceptor.java:116) at org.jboss.cache.interceptors.base.CommandInterceptor.handleDefault(CommandInterceptor.java:131) at org.jboss.cache.commands.AbstractVisitor.visitRemoveNodeCommand(AbstractVisitor.java:75) at org.jboss.cache.commands.write.RemoveNodeCommand.acceptVisitor(RemoveNodeCommand.java:125) at org.jboss.cache.interceptors.base.CommandInterceptor.invokeNextInterceptor(CommandInterceptor.java:116) at org.jboss.cache.interceptors.InvocationContextInterceptor.handleAll(InvocationContextInterceptor.java:178) at org.jboss.cache.interceptors.InvocationContextInterceptor.visitRemoveNodeCommand(InvocationContextInterceptor.java:88) at org.jboss.cache.commands.write.RemoveNodeCommand.acceptVisitor(RemoveNodeCommand.java:125) at org.jboss.cache.interceptors.InterceptorChain.invoke(InterceptorChain.java:287) at org.jboss.cache.invocation.CacheInvocationDelegate.removeNode(CacheInvocationDelegate.java:478) View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4250597#...
