Description

Right now, ExtensionLoader calls

extClazz.newInstance();

This call is deprecated in newer JDK versions. It is advised to use

return (T) extClazz.getDeclaredConstructor().newInstance();

instead in this case.

Aim(s):

• Remove the deprecated form in exchange for the recommended one.
