Force early classloading for PublishState #10273

amarziali · 2025-12-30T10:20:32Z

What Does This Do

Forces preloading PublishState enum values to avoid having this classloading happening on hot path (like decrementRefAndMaybeWrite).
This particular trick will potentially avoid classloading on VirtualThread.unmount that, closing scopes, could trigger this code path.

+    // preload this enum to avoid triggering classloading on the hot path
+    TraceCollector.PublishState.values();


suggestion:

Suggested change

// preload this enum to avoid triggering classloading on the hot path

TraceCollector.PublishState.values();

// preload this enum to avoid triggering classloading on the hot path

// This prevent an an issue with VirtualThread instrumentation

TraceCollector.PublishState.values();
