If you use EJB2 entity beans together with map-based remote EJB client configuration [EJBCLIENT-34], it seems not possible to locate entities using their EJB Home and then use them.

How to reproduce:
- Take org.jboss.as.test.integration.ejb.remote.entity.bmp.BMPRemoteEntityBeanTestCase from basic integration testsuite
- Change it so that it will use a map-based configuration instead of jboss-ejb-client.properties, for example change getHome and getProps methods like this, and add getProps method:

    private BMPHome getHome() throws NamingException {
        return (BMPHome) new InitialContext(getProps()).lookup(
                "ejb:"+APP_NAME+"/"+MODULE_NAME+"/SimpleBMP!org.jboss.as.test.integration.ejb.remote.entity.bmp.BMPHome");
    }

    private DataStore getDataStore() throws NamingException {
        return (DataStore) new InitialContext(getProps()).lookup(
                "ejb:"+APP_NAME+"/"+MODULE_NAME+"/DataStoreBean!org.jboss.as.test.integration.ejb.remote.entity.bmp.DataStore");
    }

    private Properties getProps() {
        System.setProperty("jboss.ejb.client.properties.skip.classloader.scan", "true");
        Properties props = new Properties();
        props.put("org.jboss.ejb.client.scoped.context", true);
        props.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
        props.put("endpoint.name", "client");
        props.put("remote.connections", "main");
        props.put("remote.connection.main.host", "localhost");
        props.put("remote.connection.main.port", "4447");
        props.put("remote.connection.main.connect.options.org.xnio.Options.SASL_POLICY_NOANONYMOUS","false");
        props.put("remote.connection.main.connect.options.org.xnio.Options.SASL_POLICY_NOPLAINTEXT","false");
        props.put("remote.connectionprovider.create.options.org.xnio.Options.SSL_ENABLED", "false");
        return props;
    }

- Run the testcase.

Out of the 9 tests in this testcase, 5 will fail. Those are the ones which access an entity through BMPHome.findByPrimaryKey. Calling this correctly returns a Proxy for remote EJB EntityEJBLocator, but any calls on this proxy will fail with:

java.lang.IllegalStateException: EJBCLIENT000025: No EJB receiver available for handling [appName:ejb-remote-test, moduleName:ejb, distinctName:] combination for invocation context org.jboss.ejb.client.EJBClientInvocationContext@12ca1922

When the testcase uses a jboss-ejb-client.properties file, everything works.
