How to repro:

import org.chromium.build.annotations.NullMarked;
import org.chromium.build.annotations.Nullable;

@NullMarked
public class Foo {
  public interface Supplier<T extends @Nullable Object> extends java.util.function.Supplier<T> {
  }

  public static void waitForAll(Runnable callback, Supplier... suppliers) {
  }

  public static void test(Supplier<Object> sup2) {
     waitForAll(() -> {}, sup2);
  }
}

Changing waitForAll to use Supplier<?> rather than Supplier fixes the crash.

Foo.java:16: error: An unhandled exception was thrown by the Error Prone static analysis plugin.
     waitForAll(() -> {}, sup2);
               ^
