NetworkServerControl.sysinfo() is a consideration.  It already requires
extra permissions, but this one could be problematic.

On a similar note: one thing we struggle with in  suppport  is getting
accurate sysinfo and determining which Derby  is getting loaded in
deeply embedded environments.   One enhancement I was considering filing
was to have sysinfo dump to the derby.log automatically if
derby.stream.error.logSeverityLevel=0 and permissions permit, but I was
still mulling it over  because we want to encourage more limited
permissions not more.

I wonder the best way to get this information from customers if sysinfo
is  just meant to be a quick classpath check and not a definiitive
answer to the age old question:  "what derby jars am I using?"
