The `java.io.Console` has several backends: a simple on in `java.base`, a more convenient one in `jdk.internal.le` (with line-reading based on JLine) and one for JShell.
The backend based on JLine is proving to be a somewhat problematic - JLine is very powerful, possibly too powerful and complex for the simple task of editing a line with no completion, no history, no variables, no commands, etc. As a consequence, there are inevitable sharp edges in this backend. The idea in this PR is to replace the use of JLine in the `jdk.internal.le` backend with a simple escape code interpreter, that only handles a handful of keys/codes (left/right arrow, home, end, delete, backspace, enter), and ignores the rest. The goal is to have something simple with less surprising behavior. ------------- Commit messages: - Removing trailing whitespace - 8352693: Use a simpler console reader instead of JLine for System.console() Changes: https://git.openjdk.org/jdk/pull/24242/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=24242&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8352693 Stats: 2502 lines in 22 files changed: 1872 ins; 600 del; 30 mod Patch: https://git.openjdk.org/jdk/pull/24242.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/24242/head:pull/24242 PR: https://git.openjdk.org/jdk/pull/24242
