When I run my project, I get numerous outputs of this error:

I notice that this problem has a pattern of being asked all over the web, but with no real answers. What is a general cause for this kind of error?

I had this:

 class Util {
  static boolean isNeverAsync = System.getenv().get("asyncc_exclude_redundancy").equals("yes");
}

you can probably see the problem, the env var might return null instead of string. So just to test my theory, I changed it to:

 class Util {
  static boolean isNeverAsync = false;
}

and the problem went away. Too bad that Java can't give you the exact stack trace of the error though, kinda weird.

I recently ran into this error on Windows 10. It turned out that windows was looking for .dll files necessary for my project and couldn't find them because it looks for them in the system path, PATH, rather than the CLASSPATH or -Djava.library.path

I had this same Error and it turns out, I had a method that was being called over and over, like an infinite loop, except it wasn't in an actual loop.

Realised that I was using OpenJDK when I saw this error. Fixed it once I installed the Oracle JDK instead.
