If JShell is run on a system that does not have `/bin/test` (which is, apparently, possible for some systems, which only have `/usr/bin/test`), it won't switch the terminal into the raw mode, and the input will not work properly.
The proposed fix herein is to detect whether `test` existing in `/usr/bin/test`, and if yes, use that location. Use the existing `/bin/test` otherwise. ------------- Commit messages: - 8304498: JShell does not switch to raw mode when there is no /bin/test Changes: https://git.openjdk.org/jdk/pull/13100/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=13100&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8304498 Stats: 63 lines in 2 files changed: 62 ins; 0 del; 1 mod Patch: https://git.openjdk.org/jdk/pull/13100.diff Fetch: git fetch https://git.openjdk.org/jdk pull/13100/head:pull/13100 PR: https://git.openjdk.org/jdk/pull/13100
