-----------------------------------

             Summary: 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)?
