The following exception is thrown:

Problem can be easily reproduced by a minimal case:
test.ear:
\lib\test-extension-0.0.1-SNAPSHOT.jar
test-ejb-0.0.1-SNAPSHOT.jar
where
test-extension-0.0.1-SNAPSHOT.jar contains:
CdiExtension.java:
package test.extension;
import javax.enterprise.inject.spi.Extension;
public class CdiExtension implements Extension {
    private String someString = "Some String";
    public String getSomeString() {
        return someString;
Bean1.java:
package test.extension;
import javax.enterprise.context.ApplicationScoped;
import javax.inject.Inject;
@ApplicationScoped
public class Bean1 {
    @Inject
    private CdiExtension extension;
    public String get() {
        return extension.getSomeString();
test-ejb-0.0.1-SNAPSHOT.jar contains:
EjbBean.java:
package test;
import test.extension.Bean1;
import test.extension.CdiExtension;
import javax.ejb.Stateless;
import javax.inject.Inject;
@Stateless
public class EjbBean {
    @Inject
    private CdiExtension extension;
    @Inject
    private Bean1 bean1;
    public String getSomeString() {
        return extension.getSomeString() + "\n" + bean1.get();
p.s. i seen same problem in community.oracle.com/thread/2577403 , but it happen in "war", not "ear", and seems successfully patched with patch №17424706
