In the interval since Solr graduated from the Incubator, what constitutes a
"required" notice has been clarified.  See LEGAL-59 and LEGAL-62, especially
the comments at < and <>.

The original rationale for separating NOTICE out in the transition from the
Apache License 1.1 to the Apache License 2.0 was to move the following clause:

 * 3. The end-user documentation included with the redistribution,
 *    if any, must include the following acknowledgment:
 *       "This product includes software developed by the
 *        Apache Software Foundation ("
 *    Alternately, this acknowledgment may appear in the software itself,
 *    if and wherever such third-party acknowledgments normally appear.

The presence of that requirement in a license conflicts with the GPL.  But as
Roy notes, the "GPL requires the preservation of notices even when it subsumes
all other licenses" -- so the kludge of moving it to "NOTICE" works around
the GPL incompatibility.

Were the Incubator to review Solr's licensing documentation today, I'm certain
that the project would be encouraged to pare things down -- to lower the cost
to downstream consumers, and in keeping with the modest original intent of
