URLClassLoader throws an NPE in constructor if first argument URLs[] is null.

According to javadoc, it throws a SecurityException only. It either should work without NPE, or declare for example IllegalArgumentException to be thrown - not NPE.

Code example: 
    public Status Ctor3T100() {
        TestURLClassLoader ucl = null;
               try {
                  ucl = new TestURLClassLoader(null, new ParentClassLoader(), new TestURLStreamHandlerFactory());
               } catch (SecurityException se) {
                  return checkCreateClassLoader();
               }
               return Status.passed("OKAY");

            }

this code throws an NPE at line:  ucl = new TestURLClassLoader(null, new ParentClassLoader(), new TestURLStreamHandlerFactory());

There is also a sample code which provides non-null, but empty URLs[]. It also throws an NPE later, during findClass call.
