This has been fixed with svn revision 369852,...
To test this, create a page flow and add an action to the page flow Controller such that the Jpf.Forward annotation of the action has an action attribute (rather than path) with the value being a bogus, non-existant action name. Something like the following.
name = "success",
action = "aBogusAction")
public Forward testAction()
return new Forward("success");
Before this change, the compiler would report an error. Now, the compiler will report only a warning.
