[infinispan-issues] [JBoss JIRA] Commented: (ISPN-1206) rest and memcached server modules aren't isolated and affect each other

[Galder Zamarreño (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-1206?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12618727#comment-12618727 ] 

Galder Zamarreño commented on ISPN-1206:
----------------------------------------

Btw, some important background info: The reason REST and Memcached can clash in the same cache is because the type of the key is the same. They both use String keys, so that's why it could be relatively easy to retrieve something that belongs to a REST server from a Memcached client.

> if we work with the same key with REST and memcached client at once, a server side class cast exception occurs because both work with different value representation:
> SERVER_ERROR java.lang.ClassCastException: [B cannot be cast to org.infinispan.server.memcached.MemcachedValue
> SERVER_ERROR java.lang.ClassCastException: [B cannot be cast to org.infinispan.server.core.CacheValue
> this happens when both server modules use shared cache manager
