java - Method reference static vs non static -

i've wondered how distinct between static , non static method references same name. in example have class called stringcollector has following 3 methods:
stringcollector append(string string)
static stringcollector append(stringcollector stringcollector, string string)
stringcollector concat(stringcollector stringcollector)
if want use stream<string> collect list of strings write that:
arrays.aslist("a", "b", "c").stream()
.collect(stringcollector::new, stringcollector::append, stringcollector::concat);
can see code doesn't compile. think that's because compiler can't deside, method use because each of them match functional. question now: there possible way distinct static method references instance method references?

(ps: yes code compiles if rename 1 of 2 methods. each of them.)

in case unbound reference instance method append has same arity, argument types , return value reference static method append, no, cannot resolve disambiguation method references. if don't want rename 1 of methods, should use lambda instead:

collect(stringcollector::new, (sb, s) -> sb.append(s), stringcollector::concat); 

or if want use static method:

collect(stringcollector::new, (sb, s) -> stringcollector.append(sb, s),         stringcollector::concat);
