Description
import java.io.IOException;
import java.util.Arrays;
public class Main {
public static void main(String[] args) throws IOException {
while (true) {
System.in.read();
Integer[] array = new Integer[0]; //breakpoint here
//Arrays.stream(array).filter(i -> i % 2 == 0);
}
}
}
Steps to reproduce:
1. run in debug mode
2. uncomment the line with Arrays...
3. compile/hot swap
