I was quite surprised to see the following in an answer: (emphasis mine)
For new projects, you should avoid the MPL as it has issues with the European law system. For this reason, the CDDL can be seen as the successor of the MPL.
Given that both licenses disallow to change the license but limit their scopt to files, you are still allowed to combine files under different licenses to make them together compile a single work.
Given that I was planning on using the Mozilla Public License as a licensing option for a new project that I was writing, this is a bit of a blow for me. I was planning on using it, especially since it's emerging in the 'open source market.'
What part of the Mozilla Public License is an issue with the European legal system? As the Mozilla Public License and the Common Development and Distribution License are fundamentally the same, how does the CDDL rectify the legal issue with the European legal system?
