I'm a newbie to Infinispan and have been playing with it. I think I found a bug. If a cache is empty and we have two nodes running (and the nodes must actually be on separate virtual machines -- it can't just be 2 jvm processes), and then a 2nd process on node#1 does a parallel streaming operation as follows:

final List<String> max = c
 .entrySet()
 .parallelStream()
 .map(e -> e.getKey().substring(0,1))
 .collect(() -> Collectors.toList());

You'll get the following error (the main error is I think " Invalid lambda deserialization"). NOTE: This error does NOT occur if the cache is populated with some data. I tried (reasonably hard) to trace the code, but couldn't figure out the issue, though I suspect it has something to do with deserializing an empty collector of some sort....Has anyone seen this or think this is a likely bug (as opposed to user error? I've tried many many things before posting....). Any workaround? (Or maybe it's a super easy "real" fix in the actual relevant code?)

Also, although I don't think it's pertinent, here's the cache definition:

 Configuration conf = new ConfigurationBuilder()

 String newCacheName = "distributedWithL1";
 manager.defineConfiguration(newCacheName, conf);
