RFF (12): JDK-8207954: Data for --release 11

[Erik Joelsson]

Hello Jan,

The assignment of a non existent directory looks suspect. You should be 
able assign to an empty value using ?=. On the other hand, what it looks 
like you want to achieve is having both the open and closed value on the 
command line. Then I would just change the ?= to +=.
