> 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
>
> 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:
> {{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)}}
> Here's RemoveExpiredCommand#setParameters(...):
> {{ @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++];
> }}}
> 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:
> {{ // If the provided lifespan is null, that means it is a store removal command, so we can't compare lifespan
> if (lifespan == null) {}}
> Could this be fixed by simply changing the cast at line 142 from (long) to (Long)?
