Description

This pull request updated the inclusion/exclusion documentation to state:

Regex matches are done over paths using slashes ("/") and not package names using dots ("."), so the "." in pkg.*Slow.*.class is a regex metacharacter, which happens to match any character, notably the (forward) slashes ("/") that make up the path. Slashes here are forward, even on Windows

That's not true, at least in Surefire 2.22+. I've prepared a simple reproduction. Built on Linux or macOS, Surefire will correctly skip ExampleIntegrationTest, but on Windows it will run (and fail the build).

Surefire is configured as follows:

<plugin>
    <groupId>org.apache.maven.plugins</groupId>
    <artifactId>maven-surefire-plugin</artifactId>
    <version>2.22.1</version>
    <configuration>
        <excludes>
            <exclude>%regex[it/.*]</exclude>
        </excludes>
    </configuration>
</plugin>

Per the documentation, that forward slash should work on Windows as well as Linux and macOS.

(Note: This also effects Failsafe, as one might expect.)
