The "--strict-compliance" flag tells mx that it should build each 
project with exactly the jdk version specified in the suites.py file. 
For that to work, you have to give it a path to a jdk 8 in EXTRA_JAVA_HOMES.

You can just remove the "--strict-compliance" flag, then mx will be 
happy with just a jdk 9 and "downgrade" it using the "-source" and 
"-target" flags. It shouldn't really make a difference.
