My question is:
Why am I able to find the class using
ClassLoader classLoader = this.getClass().getClassLoader();
classLoader.loadClass("org.testng.annotations.Test");
getLog().info(org.testng.annotations.Test.class.getName());
[INFO] org.testng.annotations.Test
But getting an exception when TestNG tries to find that same class?
[INFO] Type org.testng.annotations.Test not present
java.lang.TypeNotPresentException: Type org.testng.annotations.Test not
present
My assumption is that TestNG is not using the same classloader. I am
next going to dig into the TestNG code, but if someone already knew the
cause I would appreciate their help. Also, if someone could point me to
the right document, I would also be thankful.
Thank you, Michael

Sorry, I'm not sure I understand the question?
