JDK 4947890 has changed the way that system properties
are initialised from native in the launcher.
Concurrently 8130264 has removed one of those system
properties: java.awt.printerjob

4947890 seems to depend on the property being there
and probably should do nothing if it is not, but right now
we have a situation where you can get (or will) get an NPE
on start up.
Need to fix this ASAP before it escapes from jdk/client
