The above quote is from the general@ thread and was not written by anyone
on this list.

We can go ask the poster what he meant, but I am going to assume he is
either mistaken or is concerned there is a dependency on some source code.
For us, Falcon has a required dependency on a category B binary. I do
not see any information in [1] that says that is not allowed. The
installation of the modified binary package requires that you accept the
CPL license for Jburg before executing the rest of the install. Here’s
the section on Category B, partially condensed:
*How should so-called "Weak Copyleft" Licenses be handled?*
Each license in this category requires some degree of
reciprocity; this may mean that additional action is
warranted in order to minimize the chance that a user of
an Apache product will create a derivative work of a
reciprocally-licensed portion of an Apache product without
being aware of the applicable requirements.
Software under the following licenses may be included
in binary form within an Apache product if the inclusion
is appropriately labeled:
* CDDL, Versions 1.0 and 1.1 <http://www.sun.com/cddl/>
* CPL 1.0 <http://www.opensource.org/licenses/cpl1.0.php>
(I shortened this list)
By including only the object/binary form, there is less
exposed surface area of the third-party work from which
a work might be derived; this addresses the second
guiding principle of this policy. By attaching a prominent
label to the distribution and requiring an explicit action
by the user to get the reciprocally-licensed source,
users are less likely to be unaware of restrictions
significantly different from those of the Apache License.
Please include the URL to the product's homepage in the
prominent label.
(I removed a paragraph here)
This is colloquially known as the Category B list.
Also, note that the main SDK has a required Category B binary dependency
on the OSMF.swc.
