I am not a lawyer, so for an in-depth explanation of any particular wording, you may need to ask your lawyers. In general however, your questions seem to be based on confusion of what the license requires you to do if you modify Jersey sources, not what it requires you to do if you just use Jersey binaries.
And once more - a disclaimer: I am not a lawyer. You cannot take my reply as a legal argument. As with any license, you need to consult your lawyers in case you are not sure about something in the license.

I am currently helping a company assess their open-source compliance for software that they develop. They would like to use certain functions that they can pull from the .jar files in jersey-client, jersey-server, and others. They have only downloaded the .jar files, and none of the source code. The .jar files will be included in the software that is used and distributed, only so that the functions they need from the .jar files can be accessed by their other (proprietary) code. Since they are not modifying any of the code and they are not using or distributing any of the Jersey source code, are they still subject to licensing restrictions stating that they must either include or make available the corresponding source code along with the .jar files? In addition, do they have to include a LICENSE file along with the .jar files? Where can that be obtained? Lastly, if they are indeed subject to the licensing restrictions, would it be okay for them to not include the .jar files and instead require anyone using their software to download the corresponding Jersey dependencies? Thank you very much for your help.
