ViewWildcardPermission. javaSource code:

  protected void setParts(String wildcardString, boolean caseSensitive) {        wildcardString = StringUtils.clean(wildcardString);        if(wildcardString != null && !wildcardString.isEmpty()) {            List parts = CollectionUtils.asList(wildcardString.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 contain parts with only dividers.

Make sure permission strings are properly formatted.");            }        } else {            throw new IllegalArgumentException("Wildcard string cannot be null or empty. Make sure permission strings are properly formatted.");        }    }

Because the null value is inserted into the permission information, the above exception is thrown.

It is normal to remove null values.
