The following code within the first try{} generates OutOfMemory error. 
When trying to print its stacktrace NPE is thrown from method of class Throwable

public class OME {
    public static void main(String[] args) {
        try {
            char[] chars = new char[Integer.MAX_VALUE];
        } catch (Throwable e) {
            try {
                e.printStackTrace();
            } catch (NullPointerException npe) {
                System.err.println("NPE thrown:");
                npe.printStackTrace();
            }
        }
    }
}
