Crash on extensive output in debug console

Open OlliAtWork opened this issue 2 years ago • 0 comments

Flooding std-out in debug console by a JUnit test in a short amount of time seems to result in total vscode crash.

Running the given the following simple JUnit 5 "Test" results in crash:

import org.junit.jupiter.api.Test;

public class CrashTest {
  @Test
  public void crashTest() {
    for (int i = 0; i < 1_000_000; i++) {
      System.out.println((i + 1));
    }
  }
}

When releasing the output pressure with the example below, debug console can keep up and there is no crash.

@Test
public void noCrashTest() throws InterruptedException {
  for (int i = 0; i < 1_000_000; i++) {
    if (i % 1000 == 0)
      Thread.sleep(500);
    System.out.println((i + 1));
  }
}
