New Revision: 1668606
URL: http://svn.apache.org/r1668606
Log:
Merged revision 1668596 from tomcat/trunk:
When searching for SCIs use Context.getParentClassLoader instead of ClassLoader.getParent.
Thus one can provide the correct parent class loader when running embedded Tomcat in other environments such as OSGi.

<bug>57724</bug>: Handle the case in the CORS filter where a user agent
includes an origin header for a non-CORS request. (markt)
</fix>
+ <fix>
+ When searching for SCIs
+ <code>o.a.catalina.Context.getParentClassLoader</code> will be used
+ instead of <code>java.lang.ClassLoader.getParent</code>. Thus one can
+ provide the correct parent class loader when running embedded Tomcat in
