Groovy engine doesn't consider the default value assigned to the optional parameter. (engine id: org.eclipse.ease.engine.groovy)

Example:
In scripting perspective switch to the groovy engine. And then load the launch module as follows.
	loadModule('/System/Launch');
	
After loading the module try to access the launch method in it. 

launch method has two parameters in which the second one is optional. So the expectation is, even if we pass only one parameter the method should get invoked.

But for the following script it throws error like No signature of method.
	
	loadModule('/System/Launch');
	launch(launchConfig)
	
Error message:
No signature of method: Wrapping_org_eclipse_ease_modules_platform_debug$_run_closure5.call() is applicable for argument types: (null) values: [null]
Possible solutions: any(), any(), any(groovy.lang.Closure), each(groovy.lang.Closure), any(groovy.lang.Closure), each(groovy.lang.Closure)
	
It works fine if we pass two arguments.

This case happens only, if we have more than one parameters in the module. 
	

In other case, if we have a method which has only one parameter, which is mandatory, it accepts the method call without any argument.  
For Example,
Call the install method after loading p2 module.
 loadModule('/System/P2');
 install()
	
	
install method has one mandatory parameter. 
But without passing any parameter that method got invoked.
No error message was thrown.
