Created attachment 256654 [details] Example source If I use Stream.map() with a multi-line block that returns with a ternary, then use collect(Collectors.joining()), I get the following compilation error: The method collect(Collector<? super Object,A,R>) in the type Stream<Object> is not applicable for the arguments (Collector<CharSequence,capture#1-of ?,String>) If I eliminate the ternary or use the single-line lambda shortcut syntax, there is no problem. I get no compilation errors when compiling with javac.
