--------------------------------------

             Summary: Query is failing if custom classes are used inside of the cache
                 Key: ISPN-9866
                 URL: https://issues.jboss.org/browse/ISPN-9866
             Project: Infinispan
          Issue Type: Bug
          Components: Embedded Querying, WildFly modules
    Affects Versions: 9.4.5.Final
         Environment: Wildfly server with ISPN modules and ISPN subsystem to configure caches
            Reporter: Wolf-Dieter Fink


A simple query for a cache which contains User classes will fail for queries with the error below.

UserData class for the cache:
public class Test implements Serializable {
	private int testId;
	public Test(){}
	public Test(int myId) {this.testId = myId;}
	public int getTestId() {return animalId;}
	public void setTestId(int testId) { this.testId = testId;}
}

Simple EJB for test
@Singleton
@Startup
public class TestInfinispanQuery4EAPConfig {
	@Resource(lookup = "java:jboss/datagrid-infinispan/container/jdg-container/cache/EAPcache")
	private Cache<String, Object> cache;
	
	@PostConstruct
	public void LoadDBToMemory() {
		cache.put("1", new Test(2, 0));		
		cache.put("2", new Test(2, 0));		
		cache.put("3", new Test(1, 0));		
		QueryFactory queryFactory = Search.getQueryFactory(cache);
		
		Query q = queryFactory.from(Test.class).having("testId").eq(2).build();
		
		int size = q.getResultSize();
		System.out.println("result = " + size);
	}
}
