System.getProperty Change Listener

Is th开发者_运维百科ere any way to check if System.getProperty(...) value has changed ?

I strongly doubt that there is a general way since AFAIK a lot of the properties are provided by the OS and code is integrated into the VM. I mean, you could just check periodically but I'm pretty sure you've ruled that out already.

What properties exactly do you want to know about?
