OpenJDK 9 & macOS: java.lang.UnsatisfiedLinkError: Library not loaded: @rpath/libfreetype.6.dylib

Some time ago I wrote a post on how to brew and manage multiple (Adopt)OpenJDK versions on your mac - which is my current java setup. Premised so, lately I wanted to install STM32CubeMX on my (freshly formatted) laptop and I incurred in this friendly error:

Beautiful, isn't it? At first I've tried to switch to Java 8, and everything went fine. But I was really curious about why it fails with Java 9, so I digged a bit. From the error, it clearly looks like @rpath/libfreetype.6.dylib is not found. So I went to give a look in /Library/Java/JavaVirtualMachines/adoptopenjdk-9.jdk/Contents/Home/lib and... what?? libfreetype.dylib.6 is there, but not libfreetype.6.dylib! Symlinking libfreetype.dylib.6 to libfreetype.6.dylib did the trick :)
