Picocli 3.9.5

The picocli community is pleased to announce picocli 3.9.5.

This release contains a critical workaround to protect against JVM crashes when running on RedHat Linux 3.10.0-327.44.2.el7.x86_64.

Picocli 3.9.0 introduced a change in the heuristics for detecting when to emit ANSI escape sequences. As part of this change, picocli may load the org.fusesource.jansi.AnsiConsole class from the JAnsi library when not running on Windows. This may crash the JVM.

The underlying problem may be a bug in the native library in jansi 1.14, see fusesource/jansi-native#17 for details.

The workaround in this release is to only load the AnsiConsole class when running on Windows.

Users using 3.9.0 and higher are strongly recommended to upgrade to 3.9.5 or later.

Note that this issue can manifest itself when running in Gradle (e.g. continuous integration tests) even if the application itself does not have the jansi library in the classpath, since the jansi classes can be loaded from the jansi-1.14 jar included in Gradle 4.5.x.

This is the fiftieth public release.
Picocli follows semantic versioning.
