Description

https://github.com/temporalio/sdk-java/blob/master/temporal-sdk/src/main/java/io/temporal/internal/sync/DeterministicRunnerImpl.java#L336-L347

Would be useful to have a counter metric for this. Would allow detection so can fix in code if was oversight not to wait on promise,or ignore warning via something like

promise.exceptionally(e->null);
or promise.handle((ex, failure) -> null);

Research direction

Start in temporal-sdk/src/main/java/io/temporal/internal/sync/DeterministicRunnerImpl.java at lines 336-347, where unaccessed failed promises are handled. Trace the existing warning path and determine how a counter metric should represent this condition. Done means the metric is emitted for unaccessed failed promises and the behavior is covered by the relevant tests identified while reading the runner.
