JavaDocs throws illegalargumentexception

I am using IntelliJ idea. When I start generating JavaDocs (through tools - > generate Javadoc), I will throw an illegealargumentexception without information about the error

Even without Javadoc annotations, this happens when testing with each individual file in the module

This is an example of the stack trace I got:

javadoc: error - java.lang.IllegalArgumentException

As far as I know, it doesn't really tell me a lot about actual errors This is a sample file that I tried to generate JavaDocs for:

package Network;

public class NetworkTags {

    public static final String OPEN_TAG = "<";
    public static final String CLOSE_TAG = "/>";

    public static final String NET_OPEN_TAG = "<NET>";
    public static final String NET_CLOSE_TAG = "</NET>";

    public static final String VERTEX_TAG = "VERTEX";
    public static final String EDGE_TAG = "EDGE";

    public static final String REL_TAG = "REL";
    public static final String TYPE_TAG = "TYPE";
    public static final String COST_TAG = "COST";
    public static final String NAME_TAG = "NAME";

    public static final String SOURCE_TAG = "SOURCE";
    public static final String TARGET_TAG = "TARGET";

    public static final String FROM_TAG = "FROM";
    public static final String TO_TAG = "TO";
}

Using java 8 and IntelliJ idea 2016.1 one
