This upgrade is important: native code included in jansi-1.14 (included in Gradle 4.5.x) seems to have a bug that can crash the JVM.
(Version details: RHEL 3.10.0-327.44.2.el7.x86_64 on Java 1.8.0_112-b15
Java HotSpot(TM) 64-Bit Server VM (build 25.112-b15, mixed mode)).
Picocli 3.9.5 will only load jansi classes when running on Windows. Picocli versions 3.9.0 to 3.9.4 may load jansi classes when running on non-Windows platforms and are vulnerable to this problem.
