04/10/2018, 5:45 PMFYI There is a JEP for adding collection literals to java, which was also freezed. Part of the reasoning can be read up here: http://mail.openjdk.java.net/pipermail/lambda-dev/2014-March/011938.html
Maybe JetBrains reasoning for not adding collection literals is in part based on the conclusions drawn by oracle.
I wish I could find a full writeup which documents the conclusions drawn from oracles explorations in more detail 😐
