Description Dennis Huebner CLA 2012-01-26 08:54:51 EST 
Xtext
Version: 2.3.0.v201201181458
Build id: N201201181458

Implementing an generic Interface e.g. org.eclipse.emf.common.util.TreeIterator<E>
with a concrete Type e.g. File produce an error marker, see example below.

class FileTreeIterator implements TreeIterator<File> {

File next;

...

override next() {
		next
	}
...

}


Error marker: Incompatible implicit return type. Expected E but was java.io.File
Comment 1 Sebastian Zarnekow CLA 2012-01-26 09:07:37 EST 
Possibly related to

class StringList extends ArrayList<String> { }

where we see an error marker for missing implementation of #toArray.

See OverrideValidationTest.testClassMustBeAbstract_05() and ~06()
