Since I posted in the previous days about my doubts and questions and I had no answers from Jasper's team I would like to put my thoughts here and I would like to discuss civilly:
Jasper Server CE
Jasper Server CE was available in the Affero GPL license. Of course, you can change the license of the new versions but you cannot change the license of the previous version.
Proof: https://web.archive.org/web/20220708012930/https://sourceforge.net/projects/jasperserver/ So, at least, the version from 2022 is still under AGPL and to comply to AGPL, at least, those versions should be freely available with source code with a giant note
JASPER SERVER CE IS NO LONGER BEING DEVELOPED, SO BE AWARE! FEEL FREE TO FORK IT
Jasper Studio CE
Jasper Studio, even at its latest release, looks like under Eclipse Public License, which is another open-source license, and it requires too, having the source code.
Proof: https://sourceforge.net/projects/jasperstudio/ and the license you can find in the zip you can download it from Source Forge.
So where is the source repo? Did it change the license of the latest release? No problem, we have the right to have the source of the previous versions, otherwise there is a second license violation.
Jasper Report Library
At least this one is still under LGPL, at least for version 6.xx , we will see with the next version.
I would like to have your thoughts about this, even from the Jasper guys, maybe with an official statement.
