Hello David, When running configure --with-buildjdk=./jdk/build/linux-x86_64-normal-server-release/jdk
I get the following error configure: Potential Build JDK found at /opt/FaceClockJava/jdk10l/build/linux-x86_64-normal-server-release/jdk is incorrect JDK version (openjdk version "10-internal"); ignoring configure: (Your Build JDK must be version 9) checking for Build JDK... no configure: error: Could not find a suitable Build JDK configure exiting with result code 1 How do I build with buildjdk10 when it's asking for 9?
