[infinispan-issues] [JBoss JIRA] (ISPN-4212) Unable to get entries from newly started non-defined caches

[Martin Gencur (JIRA)]

    [ https://issues.jboss.org/browse/ISPN-4212?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12963184#comment-12963184 ] 

Martin Gencur commented on ISPN-4212:
-------------------------------------

I'm looking into this. The entry is really stored in the cache via put operation but can't be retrieved via get(). This points to the Equivalence classes that are badly configured. Currently, all caches that are defined in the XML file and started at the beginning have keyEquivalence and valueEquivalence equal to org.jboss.as.clustering.infinispan.equivalence.AnyServerEquivalence while cache started later have org.infinispan.commons.equivalence.AnyEquivalence. I will look for the right fix.

> If you use hotrod to put entries into a cache which is not defined in standalone.xml, it will be started:
> {code}
> 15:35:50,676 INFO  [org.jboss.as.clustering.infinispan] (HotRodServerWorker-1) JBAS010281: Started nonDefinedCache cache from local container
> {code}
> but when you try to retrieve the entry back, you'll get null.
> {code}
> RemoteCacheManager rcm = new RemoteCacheManager(new ConfigurationBuilder().addServer().host("localhost").port(11222).build());
> RemoteCache<String, String> cache = rcm.getCache("nonDefinedCache");
> cache.put("key", "value");
> cache.get("key"); // returns null
> {code}
> Happens in the current server snapshot.
> A while back you'd get this
> {code}
> WARN: ISPN004005: Error received from the server: org.infinispan.server.hotrod.CacheNotFoundException: Cache with name 'nonDefinedCache' not found amongst the configured caches
> {code}
> So it seems we're somewhere in the middle now (not throwing exception, but also not working). The documentation here is also wrong https://github.com/infinispan/infinispan/blob/master/client/hotrod-client/src/main/java/org/infinispan/client/hotrod/RemoteCacheManager.java#L511 .
