Release Note: Default Console Implementation No Longer Based On JLine - Resolved
Description
JDK has been using JLine based Console implementation, in JDK20 as opt-in, then in JDK22 as the default. While it has been providing rich functionality for Console, it is increasingly difficult to maintain as a Console implementation. In light of the on-ramp feature (https://bugs.openjdk.org/browse/JDK-8344699), which proposes switching `java.lang.IO` class to use `System.in` and `System.out` instead of Console, reverting the default Console implementation to JDK's built-in one in the java.base module is considered desirable.
