#49 BSF4ooRexx on macOS Catalina failing launch of ooRexxTry
After a successful installation of BSF4ooRexx, when starting the oorexx.app application to launch the BSF4ooRexxMenu The following warning below appears:
java -cp "/Applications/ooRexx.app/Contents/MacOS" BSF4ooRexxMenu & exit;
po@POs-16Core-Mac-Pro ~ % java -cp "/Applications/ooRexx.app/Contents/MacOS" BSF4ooRexxMenu & exit;

zsh: you have running jobs.

BSF4ooRexxMenu nevertheless launches and everything seems to work as intended. It is possible to uninstall from Installation -> uninstall menu item BUT When trying to use ooRexxTry from the Open Obejcr Rexx menu item this error message occurs:

Someone needs to look into this.
NOTE: ooRexx itself works as it should from a terminal session and the test suite for ooRexx passes all tests that the standalone ooRexx passes.
This warning comes from the modular Java introduced with Java 9. Eventually this warning will be turned into an error. It stems from using java.lang.reflect. BSF4ooRexx has a second reflection mechanism introduced that uses java.lang.invoke which is needed starting with modular Java 9. As java.lang.invoke is fully implemented in Java 8 this new reflection mechanism will be used for that version already. Java's warning is misleading in this case and when turned into an error it will not affect BSF4ooRexx.
