> In prior JDK releases, `System.console()` could return a `Console` instance > even when the JVM was not attached to an interactive terminal. This could > lead to confusion, particularly when input was not from a keyboard or output > was redirected, such as to or from a file or pipe, especially when using > methods like `readPassword()`. Starting with JDK 25, the default behavior has > changed: `System.console()` now returns `null` if standard input and/or > output is redirected. However, if a JLine-based Console implementation is > explicitly specified via the system property `-Djdk.console=jdk.internal.le`, > the previous behavior may still occur. > This PR aims to align the behavior of the JLine-based `Console` > implementation with the default `System.console()` behavior. The actual code > change is a one-liner in `JdkConsoleProviderImpl.java`; the rest of the > changes are adjustments to test cases to reflect the updated behavior. A > corresponding CSR has also been drafted.
