Default JAI-core acceptable in non-free?

I have been trying to find out whether jai-core (java advanced
imaging) is acceptable for distribution in 'non-free'.
It's a library that is used by (among others) a large number of open
source java GIS applications.

>From the website:

The source code for the jai-core project is licensed under the Java
Research License (JRL) for non-commercial use. The JRL allows users to
download, build, and modify the source code in the jai-core project
for research use, subject to the terms of the license.
https://jai-core.dev.java.net/source/browse/jai-core/LICENSE-JRL.txt?rev=1.1&view=markup

The source for the jai-core project is also licensed for commercial
use under a new no-fee Java Distribution License (JDL). The JDL allows
commercial use of Java Advanced Imaging with or without modification,
as long as compatibility with the entire API Specification is
maintained. This includes passing the TCK tests for Java Advanced
Imaging, and retaining the javax namespace as defined by the JCP.
https://jai-core.dev.java.net/source/browse/jai-core/LICENSE-JDL.txt?rev=1.1&view=markup

I have no experience at all, but the second license 'JDL' seems quite
problematic, but I wonder if the first one (Java research license) is
acceptable for non-free.

Thanks for your reviewing. I have the same doubts about JAI and dependent
software. That would require moving openjump in contrib in order to have
it updated to current 1.3 with raster support.
I would also add that currently OsGeo incubation for OpenJump has been
stalled because proejct team has not the energy
to follow up OsGeo requirements. Note that OpenJump is also a pre-requirement
for Degree (currently an OsGeo project) AFAIK, which renders the whole thing
quite weird.

Currently OpenJump 1.0 is almost usable, but it has a few problems with some
menu entries that cause some non fatal exceptions and usual ipv6 problem.
I wonder if we have still to support it as is.

Not just Openjump,
Almost any java gis program relies on jai (geotools library, kosmo
gis, gvSig, openjump, udig, diva gis, ...).
I have not yet done a lot of research (and my knowledge of java is too
small to do it quickly) but it might be possible to separate the core
functionality to main and other modules to contrib. On the other hand
I don't think many users would prefer af fully free package with
almost no grid/image facilities over a contrib package which includes
more functionality.

I cannot judge on whether we should support Openjump 1.0, but it would
be nice if we could one day create gvSIG and geotools packages. This
are really projects with a large momentum. A well working JAI package
is definitely useful for packaging them (although it is certainly not
the only thing needed).
