About Thread.currentThread().getContextClassLoader()

[Andrej Fink]

Thread.currentThread().getContextClassLoader() is actively used in io.smallrye.common.classloader.ClassPathUtils

but from technical perspective it could be null:

• there is a setter
• I have seen such situation

It is safer to add utility method

[public] static ClassLoader getClassLoader () {
    ClassLoader cl = Thread.currentThread().getContextClassLoader();
    return cl != null ? cl
        : ClassPathUtils.class.getClassLoader();
}
