Description Moritz Eysholdt CLA 2013-06-12 09:06:31 EDT 
If you set a breakpoint in Java code that has been generated by an active annotation the debugger will never stop at that breakpoint, even though the corresponding Java statement is executed. 

I assume this is because there are not line mappings to Xtend code for that Java line.
Comment 1 Stefan Oehme CLA 2014-07-16 09:15:22 EDT 
The line information is missing because the expressions have no source element. 

With the new Associator#setPrimarySourceElement the situation has at least somewhat improved since you can now set breakpoints on the signatures of methods/constructors.
Comment 2 Stefan Oehme CLA 2014-07-17 02:38:21 EDT 
This is not limited to active annotations. Many breakpoints in the Java code are not hit.

package foo

class Foo {
	
	def static void main(String[] args) {
		println(new Foo().getBar())
	}
	
	def getBar() {
		"bar"
	}
}

Set a breakpoint in the getBar() method in the generated Java code and debug the main method. It doesn't stop.
