Crash issue with GraalVM

[stef-pellegrino]

The "Port forwarding" sample does not work with this configuration:

• Java 22
• Windows 11
• Last release of GraalVM (java 22.0.1-graal)

Works perfectly with fat .jar (JVM), but crashes badly when compiling against "native-image"

[brett-smith]

Synergy has a few features that are currently using reflection. This means those particular features will not work with native image without some extra meta-data.

You can either run the example once with the native image tracing agent enabled, or you can hand-craft a META-INF/native-image/synergy/reflect-config.json resource and bundle it inside your jar before native compilation.

I just gave the example a quick try, and can confirm this is needed in this case. Add the following to reflect-config.json.
