Problem when querying to different entity types
I want to use two infinispan caches with different object types stored in them. Storing the objects and accessing them through their keys works fine. But when using the query DSL to find specific object in the caches my code fails with an
java.lang.IllegalStateException: Unknown entity name org.project.Relation
exception.
I run the following code to setup my caches:
DefaultCacheManager manager = new DefaultCacheManager("infinispan.xml");
Cache<String, Resource> resourceCache = manager.getCache("Resources");
QueryFactory<LuceneQuery> resourceQueryFactory = Search.getQueryFactory(resourceCache);
Cache<String, Relation> relationCache = manager.getCache("Relations");
QueryFactory<LuceneQuery>relationQueryFactory = Search.getQueryFactory(relationCache);
When using the query DSL to search the resources cache first and then the relations cache I get the following stack trace:
java.lang.IllegalStateException: Unknown entity name org.project.Relation

Running a test where only one of the caches is searched works fine. So I assume this is not caused by the specific query or the type of objects I store in the cache, but by trying to search for two different types.
I am using Infinispan 7.1.1 with the following configuration:
<infinispan>
<cache-container default-cache="default" statistics="true" name="Repository">
<local-cache name="default" statistics="true">
<transaction
transaction-manager-lookup="org.infinispan.transaction.lookup.DummyTransactionManagerLookup"
mode="NON_XA" locking="OPTIMISTIC" />
<indexing index="LOCAL">
<property name="default.directory_provider">ram</property>
</indexing>
</local-cache>
</cache-container>
</infinispan>
What am I doing wrong here? Is there anything I need to configure?
Thanks in advance, Tobias
