How to access default scoped method of one jar from another jar in EAP 6?

Issue

• There are 2 EJB module in an EAR. In one module, there is a class ejb.one.TestPojo.java with a method void helloWorld(String str){} and in the second module, there is a class ejb.one.Pojo.java, which will invoke a TestPojo.helloWorld(String) and the <ear-subdeployments-isolated> attribute of the EAR is already set to false. But still JBoss is throwing the following ERROR from the class ejb.one.Pojo.java while accessing the method helloWorld(String) of class ejb.one.TestPojo.java:

Caused by: java.lang.IllegalAccessError: tried to access method ejb.one.TestPojo.helloWorld(Ljava/lang/String;)Ljava/lang/String; from class ejb.one.Pojo
