Galder Zamarreño commented on ISPN-5449:
----------------------------------------

Based on your description, seems like you are starting your own Hot Rod server in the code instead of running the Infinispan Server itself. Do you get the same issue if you are running against standalone Infinispan Server and putting your configuration in the server itself?

You seem to have all the pieces to create a unit test, since you create your own HR server, building the cache manager behind it...etc. For compatibility test ideas, you should check here: https://github.com/infinispan/infinispan/tree/master/integrationtests/compatibility-mode-it/src/test/java/org/infinispan/it/compatibility

Finally, if you want to keep compatibility enabled, and you want the server to store data in byte[] format, you should not enable  {{storeAsBinary}}. Instead, you should disable that, and set {{dataContainer.valueEquivalence}} to {{org.infinispan.commons.equivalence.ByteArrayEquivalence}}. This scenario is tested in https://github.com/infinispan/infinispan/blob/master/integrationtests/compatibility-mode-it/src/test/java/org/infinispan/it/compatibility/ByteArrayValueDistEmbeddedHotRodTest.java test

> Hi,
> I'm going to  upgrade to Infinspan 7.2.1final but I got into a showstopper. This error occours very frequently and the cluster becomes not usable.
>  
> In dev enviroment I'm using only Java HotRod clients and 3 Java HotRod Servers. When I put a "byte[]" in a cache then the following error occurs.
> Using only one Hotrod server the error does not occur.
