Installing packs in Eclipse fails

I just put in a fresh install of Eclipse to begin development of a STM32 based project on a new Windows 10 machine.

I've gone through the Eclipse Marketplace and installed "GNU MCU Eclipse 4.7.1".  When going to the C/C++ Packs view, I click the "refresh" button to register all available packages, but the thing fails right away.  The relevant console output is below:

Update packs job started.
Parsing "">www.keil.com/.../index.pidx"...
org.xml.sax.SAXParseException; lineNumber: 1; columnNumber: 50; White spaces are required between publicId and systemId.
File "C:\Users\xxxxxx\AppData\Roaming\CMSIS-Packs\.cache\.content_www_keil_com_pack_index_pidx.xml" written.

Does anyone have any idea what's going on here?  I find it unlikely that the hosted package index is throwing an error.
