Compiled native image crashes with above exception because of some Swing stuff hasnt been ported to the GraalVM compiler yet.

Tested on Windows. Not sure about other platforms.

Relevant github issues:

• [native-image] Swing application cannot be compiled on Windows oracle/graal#3659 [native-image] Swing application cannot be compiled on Windows
• [native-image] java.home property not set oracle/graal#1812 [native-image] java.home property not set

fixed in 80b80c8

java.home is not set on native-image executables because they are standalone. As a workaround we set the working dir to java.home and copy some dependencies/resources into it so they can be found.

However this now opens the door for #2
