Description

I was experimenting with @Delegate and noticed that if the underlying class throws an exception, the delegating class has no line number.

Would be a nice enhancement to have the stack trace reference the line where the delegation was declared.

See attached example script which should show this output:

Foo!
Caught: java.lang.Exception: blow up with bar
java.lang.Exception: blow up with bar
	at Lower.blowup(delegatetest.groovy:15)
	at Lower$blowup.call(Unknown Source)
	at Upper.blowup(delegatetest.groovy)      # no line number here
	at Upper$blowup.call(Unknown Source)
	at delegatetest.run(delegatetest.groovy:25)
