They've been giving us shit because they "see downloads from our IP addresses". It's an absolute shake-down operation. They let anybody download their poisoned jvm for free and then tell your company that they now owe them a fortune.
I know it may not be an easy question to answer, but does your company really owe them money? I’m guessing that their other software that uses their JVM also has a license, so they should be more clear about the company having to license out the JVM in order to use it. This sounds like a scam that comes packaged along with some other software.
It's not about functionality. When you're paying for licensing and support you need to use supported versions of things. If you call up about an issue with the database and you're running an unsupported os or Java version they hang up on you.
