the file and rebuild and verify if the compiler options are the same (and
that both builds use the same compiler)...

To avoid all possible side effects, I deliberately tested Oracle Jdk (ea
binary builds). I hope both were compiled with the same gcc & options.

You're right: I guessed there was c macros, so I compared both
java2d/folders too (including header files).

I can try compiling both openjdk 8 & 9 sources on my laptop but it may take
some time to test again.

PS: I think it is better for me to focus on improving patch 4.
