Long stacktrace is to trace the call stack from both synchronous and asynchronous function invocations. This project is a proof-of-concept application to implement a long stack trace functionality in java.
The demo main function is
public static void main(String[] args) throws InterruptedException {
ExecutorService executorService = Executors.newCachedThreadPool();
executor = new LongStackTraceExecutor(executorService);
CompletableFuture.runAsync(() -> {
CompletableFuture.runAsync(() -> {
CompletableFuture.runAsync(() -> {
LongStackTraceExecutor.dumpStack();
}, executor);
}, executor);
},executor);
}The result stack trace is
