Is there any possible way to set system property during runtime of virtual machine from outside world.
For example: I start some app that will work for a long time. I start it with property -DmyProp=myVal. While this app is working, I want to change myProp to "otherVal", but I don't want to do it from within app. I want to change that property from OS (or something like that) because I want to have possibility to set it on runtime, and I don't want to modify code of this app.
