jOOλ - The Missing Parts in Java 8 jOOλ improves the JDK libraries in areas where the Expert Group's focus was elsewhere. It adds tuple support, function support, and a lot of additional functionality around sequential Streams. The JDK 8's main efforts (default methods, lambdas, and the Stream API) were focused around maintaining backwards compatibility and implementing a functional API for parallelism.
In jool 0.9.9 - See screen grab from Eclipse - the error message is
"The method collect(Collector<Object,capture#1-of ?,List<Object>>) is undefined for the type Seq<String>"
I'm not sure if this only happens in Eclipse or more generally, I think it is worth fixing either way (should be fixable by moving the default collect implementations into Seq).
