Bug#573482: Jackrabbit 1.5 License not free? for Debian/Ubuntu inclusion

Following is a response from Stefan Guggisberg.

So the Jackrabbit is Apache Licensed, where the JSR-170 (JCR API) JAR is
licensed under the license below.

I don't think there is a problem with this license to be included in
anything, except the fact the JCR's source code is not available. Is it
really not possible that the JCR JAR be included into Debian as a binary

The JSR-170 license ( http://www.day.com/maven/jsr170/jars/LICENSE.txt )

In addition to the permissions granted under the Specification

IANAL and certainly not familiar with the Debian and Ubuntu license
terms. here's the relevant JCR 1.0 specification license:

and a related post:
