Possible bug if doing parallelstream (distributed) computation on *EMPTY* cache?
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 may things before posting....). Any workaround? (Or maybe it's a super easy "real" fix in the actual relevant code?)
