Class VirtualThreadExecutorMetricsTest

java.lang.Object
ubic.gemma.core.metrics.binder.VirtualThreadExecutorMetricsTest
public class VirtualThreadExecutorMetricsTest extends Object
Verifies that VirtualThreadExecutorMetrics correctly increments its counters/gauges when wrapped tasks are submitted, complete, or throw. Uses a cached thread pool as the delegate (not the VT executor itself) so the test runs identically on JDK 17 and 21 — the wrapper's instrumentation is independent of the underlying ExecutorService implementation.
