@SdkInternalApi
public final class WarmUpDiscovery
extends Object

Shared best-effort helpers for the CRaC warm-up paths: ServiceLoader iteration and running a single warm-up task without letting its failure stop the others.

Method Summary

static <T> void	forEachDiscovered(Iterator<T> iterator, Consumer<T> action)	Applies action to every discovered element, skipping (and logging at warn) any element that fails to load or whose action throws, so the rest still run.

Method Details

forEachDiscovered

public static <T> void forEachDiscovered(Iterator<T> iterator,
 Consumer<T> action)

Applies action to every discovered element, skipping (and logging at warn) any element that fails to load or whose action throws, so the rest still run. Logs at debug when nothing is discovered.

runSafely

public static boolean runSafely(String description,
 Runnable task)

Runs one warm-up task. Returns true if it completed. If it fails, logs at warn with description and returns false, so a sibling task still runs.

Also catches LinkageError: a task can fail to link (missing dependency or native library) and that is an Error, not an Exception. Other errors still propagate.
