Hi,it may be unrelated to these relaunches, but I have been wondering for awhile, what the toolkit parameter in the <fx:application> ant element is supposed to do.
see: https://docs.oracle.com/javase/8/docs/technotes/guides/deploy/javafx_ant_task_reference.html#CIAGCAFHAt least in my tests changing the parameter had no effect on the generated jnlp file.
