Take a look at the wildcardpermission.java source code:

  protected void SetParts (String wildcardstring, Boolean casesensitive) {wildcardstring = Stringutils.clean (WILDCA        rdstring); if (wildcardstring! = null &&!wildcardstring.isempty ()) {List parts = collectionutils.aslist (wildcards            Tring.split (":"));            This.parts = new ArrayList ();            Iterator i$ = Parts.iterator ();                while (I$.hasnext ()) {String part = (string) i$.next ();                Set subparts = Collectionutils.asset (Part.split (","));                if (!casesensitive) {subparts = This.lowercase (subparts); } if (Subparts.isempty ()) {throw new IllegalArgumentException ("Wildcard string cannot Co Ntain parts with only dividers.                Make sure permission strings is properly formatted. ");            This.parts.add (subparts); } if (This.parts.isEmpty ()) {throw new IllegalArgumentException ("WildcarD string cannot contain only dividers. Make sure permission strings is properly formatted. ");} else {throw new IllegalArgumentException ("Wildcard string cannot be null or empty.) Make sure permission strings is properly formatted. ");}

Because you inadvertently insert a null value into the permission information, the result throws the above exception.

Normal after removing null values.
