Description

We often see incorrect line number reports for Groovy scripts. The attached "onload.groovy" script (builds a Swing UI) has a syntax error on line 103: The "new StateMonitor()" instantiation is missing "()". When parsing we however get an error on line 15:

Unexpected input: '{' @ line 15, column 38.
   ControlPanel ui = new ControlPanel() {

 

This poor error line detection makes it very hard to debug larger scripts
