Apache projects can determine the compatibility by themselves.
The main principle to bear in mind is that the license must not
impose restrictions that go beyond the terms of the Apache License 2.0

Looking at the hsqldb-1.7.3 license it seems clear and okay.
Apache Cocoon has been using it for ages.

If your PMC has difficulty understanding a complex license, then
your committers can try asking on legal-discuss@a.o (only open to
Apache committers).

The other thing that your project must do is to conform with the terms
of their license, e.g. provide a copy of the license; don't use their
name to "endorse or promote"; etc.

Look at some other Apache projects to see how they structure their
license situation, e.g.
Note how we have each license next to their *.jar file with the same
basename. Also see our NOTICE.txt how we put them there if their
license requires us to give attribution.

Hope that helps.
