Static initializer is impossible.

[gallandarakhneorg]

Static initializer syntax is not allowed. For example, it is not possible to write the SARL equivalent to:

public class Messages extends NLS {
	private static final String BUNDLE_NAME = "io.sarl.eventdispatching.messages"; //$NON-NLS-1$

	public static String BehaviorGuardEvaluator_0;
	public static String BehaviorGuardEvaluator_1;
	public static String BehaviorGuardEvaluatorRegistry_0;

	static {
		// initialize resource bundle
		NLS.initializeMessages(BUNDLE_NAME, Messages.class);
	}

	private Messages() {
	}
}

According to the Xtend forum (because the SARL OOP is strongly inspired by Xtend), static initializers should be written with block expressions as initializers.
It example above becomes in SARL:

final class Messages extends NLS {

	private static val BUNDLE_NAME = {
		val name = "io.sarl.eventdispatching.messages"
		// initialize resource bundle
		NLS.initializeMessages(name, typeof(Messages))
		name
	}

	public static var BehaviorGuardEvaluator_0 : String
	public static var BehaviorGuardEvaluator_1 : String
	public static var BehaviorGuardEvaluatorRegistry_0 : String

	private new {
	}

}
