currently there is IMHO no means in java to access/inquire the uptime of the operating system. It would be useful to have this information i.e. to decide if the wrapper is started because of a system boot. The environment variable could provide the startup time in seconds and can be used in specifying a custom (java) system property.
I think the system uptime could be easy determined in the native wrapper code for every OS.
Integrating a method in the wrapper java API would be also a solution, but this requires the use of this API.
Please add a such Variable. Thank you.
