> There are some standard JDK APIs that are not part of the 
> mapreduce.job.classloader.system.classes property value.
> Currently the default value covers only "java.,javax." from the JDK. However, 
> there are other APIs that are as well-established as these, such as 
> org.w3c.dom and org.xml.sax. In other similar systems (e.g. OSGi), it is a 
> standard practice to include both of these packages in the system classes. We 
> should add these to the default values.
