CXF-7349: NPE when thread context classloader is null
A null context classloader is valid - it means that the JVM's boot
classloader is the context. When using the ClassLoaderUtils class, there are a
few places where we get the thread's context classloader, but don't check it
for null before invoking methods on it - such as getResource/getResources/etc.
This change ensures that we get a non-null classloader by using the system
classloader when the current thread context classloader is null.

CXF-7349: Resolve NPE when TCCL is null
----
> NPE in ClassLoaderUtils
> -----------------------
>
> Key: CXF-7349
> URL: https://issues.apache.org/jira/browse/CXF-7349
> Project: CXF
> Issue Type: Bug
> Components: Core
> Affects Versions: 3.1.11
> Reporter: Andy McCright
> Fix For: 3.2.0, 3.1.12
>
>
> A NullPointerException can be thrown when the JVM's boot classloader is set
> as the thread's context classloader. Ex:
> URL url =
> Thread.currentThread().getContextClassLoader().getResource(resourceName);
> The call to getContextClassLoader() could return null - that is a valid
> return from that method. In that case, we should use
> ClassLoader.getSystemClassLoader() instead.
> This issue was reported on in the users mailing list:
> http://cxf.547215.n5.nabble.com/NPE-in-cxf-core-ClassLoaderUtils-possible-bug-td5780007.html
