Description Ed Willink CLA 2018-04-27 06:57:37 EDT 
ATL2QVTr has a helper

query getHelper(element : atlMM::LocatedElement[1]) : atlMM::Helper[1] {
	element->closure(e : ocl::OclElement | e.oclContainer())->selectByKind(atlMM::Helper)->any(true)
		}

that may fail if any() has an empty source.

The generated Java does not cache the exception. It does not even catch the exception that is just a pattern matching failure, not an transformation failure.
