CPU architecture validation plugin

Checks if the JVM is started for the real CPU architecture to avoid performance overhead of running Rosetta.

How it works (macOS X)

If the JVM architecture is "x86_64" and the OS is "Mac OS X", the plugin executes the following command:

sysctl -n machdep.cpu.brand_string

to ensure if it's a Rosetta emulation or not.

How it works (Windows)

If the JVM architecture is "amd64" and the OS is "Windows 11", the plugin checks the PROCESSOR_IDENTIFIER environment variable to ensure if it's a CPU emulation or not.

Usage

Add to the root pom.xml:

<build>
    <plugins>
        <plugin>
            <groupId>com.github.seregamorph</groupId>
            <artifactId>jvm-arch-maven-plugin</artifactId>
            <version>0.1</version>
            <inherited>false</inherited>
            <executions>
                <execution>
                    <id>jvm-arch</id>
                    <goals>
                        <goal>jvm-arch</goal>
                    </goals>
                </execution>
            </executions>
        </plugin>
    </plugins>
</build>

Supported operating systems:

• Windows (both Intel- and ARM-based)
• macOS (both Intel- and ARM-based)

For other operating systems like Linux this plugin is just no-op.
