The CORBA docs have internal paths embedded in the HTML. Admittedly, they're sort-of useless, but that just makes it even sillier to have them there.

For example, look at /scratch/HUDSON appearing in http://download.java.net/java/jdk9/docs/api/org/omg/CosNaming/NamingContextExtPackage/InvalidAddress.html

<div class="block">org/omg/CosNaming/NamingContextExtPackage/InvalidAddress.java .
 Generated by the IDL-to-Java compiler (portable), version "3.2"
