The developer is Johan Sorel, who is on this list. Maybe he can comment.

JSR-275 has been rejected by the JCP, so this project is theoretically
dead. However its former leader, Werner Keil, is considering to start a
new JSR attempt. That would be the third! But he got support from
various communities. I do not yet have a clear picture about the future,
but the choices are:
* Werner succeed in starting a new JSR, in which case I would keep the
JSR-275 dependency unchanged until the new JSR has some prototype,
in order to reduce compatibility break (assuming that the new JSR
keep the javax.measure.unit package name).
* We get confirmation that no JSR will be restarted, in which case I
will replace all current JSR-275 dependency by a
org.unitsofmeasurement interface with a custom implementation.
Wermer's effort is ongoing right now, so I plan to wait a few months to
see what come out. In the main time, we are forced to deal with current
Unit using special cases like if (unit == NonSI.FOOT) symbol = "ft"; Of
course this is not very convenient, but hopefully will be resolved some day.

We have an issue with Apache's wiki lately, so I was not able to edit
the Apache SIS wiki page. But the roadmap is:
* Apache SIS 0.4 release candidate as soon as I have completed the two
o Support of WKT 2 (a.k.a. ISO 19162) formatting - this work is in
progress right now
o Review of the Shapefile datastore base started by an other
* Release of Geotk 4.0-M1 milestone right after SIS 0.4 release.
* Removal of deprecated Geotk classes that moved to Apache SIS.
* New "port Geotk classes to SIS, then deprecate the ported Geotk
classes" cycle. The next cycle toward Apache SIS 0.5 will include:
o Map projections
o EPSG database
* At some point in the future (timeline not yet determined), Geotk and
Geotk-pending will be merged in a single project.

Thanks for the feedback :-). I also wish to start a JDK8 branch on SIS
soon, hopefully after SIS 0.4 release.
