The meaning of the java.vendor property?

Hi Bernd,

from my understanding you can choose to freely set the following
properties (and we do that for SapMachine, as you can see):

    java.vendor = SAP SE
    java.vendor.url =
    java.vendor.url.bug =
    java.vm.vendor = SAP SE

The following "specification.vendor" properties have to show the Java
SE spec lead (which currently is Oracle) so you shouldn't change them:

    java.specification.vendor = Oracle Corporation
    java.vm.specification.vendor = Oracle Corporation
