Traces are silently failing on opentelemetry-1.23.0

[rossabaker]

At least locally with Jaeger.

I can reproduce it in plain Java. Works with 1.22.0. Works with Thread.sleep. Does not work on 1.23.0 without Thread.sleep.

import io.opentelemetry.api.GlobalOpenTelemetry;
import io.opentelemetry.api.OpenTelemetry;
import io.opentelemetry.api.common.Attributes;
import io.opentelemetry.api.trace.Span;
import io.opentelemetry.api.trace.Tracer;
import io.opentelemetry.context.Scope;
import java.io.InputStream;
import java.util.logging.LogManager;

class PlainAssJava {
    public static void main(String[] args) throws Exception {
        InputStream in = PlainAssJava.class.getClassLoader().getResourceAsStream("logging.properties");
        LogManager.getLogManager().readConfiguration(in);
        OpenTelemetry openTelemetry = GlobalOpenTelemetry.get();
        Tracer tracer = openTelemetry.getTracer("plain-ass-java", "1.0.0");
        Span span = tracer.spanBuilder("my span").startSpan();
        try (Scope ss = span.makeCurrent()) {
            // In this scope, the span is the current/active span
        } finally {
            span.end();
        }
        // Thread.sleep(10000);
    }
}

Reported upstream. It may be our misuse, but it happens without otel4s in the picture at all:

open-telemetry/opentelemetry-java#5218

Fixed by 1.23.1, which Steward will be serving up soon.
