[infinispan-issues] [JBoss JIRA] (ISPN-6071) NullPointerException when executing RemoveExpiredCommand

NullPointerException when executing RemoveExpiredCommand -------------------------------------------------------- Key: ISPN-6071 URL: https://issues.jboss.org/browse/ISPN-6071 Project: Infinispan Issue Type: Bug Components: Expiration Affects Versions: 8.0.2.Final Reporter: Jason Hoetger Assignee: William Burns Fix For: 9.0.0.Alpha2, 8.1.4.Final, 8.2.2.Final I'm running Infinispan 8.0.2 in a clustered environment with a replicated cache with a single file cache store. I'm seeing some NullPointerExceptions when Infinispan executes the RemoveExpiredCommand. Here's a snippet from the stack trace: {noformat} ISPN000136: Error executing command RemoveExpiredCommand, writing keys [...large key here...] ... Caused by: java.lang.NullPointerException: null at org.infinispan.commands.write.RemoveExpiredCommand.setParameters(RemoveExpiredCommand.java:142) {noformat} Here's RemoveExpiredCommand#setParameters(...): {code} @Override public void setParameters(int commandId, Object[] args) { if (commandId != COMMAND_ID) throw new IllegalStateException("Invalid method id"); int i = 0; commandInvocationId = (CommandInvocationId) args[i++]; key = args[i++]; value = args[i++]; lifespan = (long) args[i++]; }{code} Line 142 is the cast of assignment of {{args\[3\]}} to primitive type long, which is causing the NPE. lifespan is actually a Long, not a long, and the {{perform()}} method seems to anticipate null lifespans at line 72: {code} // If the provided lifespan is null, that means it is a store removal command, so we can't compare lifespan if (lifespan == null) {}{code} Could this be fixed by simply changing the cast at line 142 from (long) to (Long)?
