Hi Robert,
sorry for the delay.

I pushed the "g0hl1n/jdk8-fix" branch to the meta-java git repository.
It is a temporary test branch and it should fix the GCC version
dependencies (as long as you have GCC >= v6).

It would be great if you could do a quick test and give me feedback ;-)

thanks & regards;rl
