     Your "verification" is wrong, with 99.44% probability.  Could you
provide an SSCCE?  Here's mine:

import java.util.Arrays;
import java.util.HashMap;
import java.util.Map;
public class Foo {
    public static void main(String[] unused) {
       HashMap<String, String[]> devObjectMap = new HashMap<String, 
String[]>(5);
       devObjectMap.put("DataExtension", new String[]{"ADLN_Customer", 
"ADLN_Story"});
       devObjectMap.put("Email", new String[]{"ADLN", "DRLN"});
       devObjectMap.put("EmailSendDefinition", new String[]{"ADLN", 
"AILR"});
       devObjectMap.put("ImportDefinition", new 
String[]{"ADLN_Customer", "ADLN_Story", "AILR_Customer"});
       devObjectMap.put("ContentArea", new String[]{"All_Subject_Lines", 
"Date_issue"});

       for (Map.Entry<String, String[]> me : devObjectMap.entrySet()) {
          System.out.printf("\"%s\" -> %s%n", me.getKey(), 
Arrays.toString(me.getValue()));
       }
    }
}

... and the output is:

run:
"ContentArea" -> [All_Subject_Lines, Date_issue]
"DataExtension" -> [ADLN_Customer, ADLN_Story]
"EmailSendDefinition" -> [ADLN, AILR]
"Email" -> [ADLN, DRLN]
"ImportDefinition" -> [ADLN_Customer, ADLN_Story, AILR_Customer]
