Description

(On non-Windows platforms:) currently, when jdk.internal.le (which is the JLine 3 library) switches terminal to raw mode, it will call several external programs to do that.

The task herein is to avoid the invocation of external programs on selected platforms by directly invoking the native functions that would switch the terminal.

Comments

Unfortunately this broke the AIX build (see https://bugs.openjdk.org/browse/JDK-8308624 ). The description "avoid the invocation of external programs on selected platforms " sounds like a fallback would be provided on the other platforms than the "selected" ones. But this seems not to be the case.
