Description Christoph Laeubrich CLA 2021-05-06 09:35:53 EDT 
Currently WritableList do no overwrites

org.eclipse.core.databinding.observable.list.ObservableList.iterator()

this leads to 

java.lang.UnsupportedOperationException
	at org.eclipse.core.databinding.observable.list.ObservableList$1.remove(ObservableList.java:126)

using an iterator to remove elements from the list.
Comment 1 Christoph Laeubrich CLA 2021-05-06 09:50:14 EDT 
The same applies to 

org.eclipse.core.databinding.observable.list.ObservableList.listIterator(int)

e.g. a Collections.sort(writeableList) throws 

java.lang.UnsupportedOperationException
	at org.eclipse.core.databinding.observable.list.ObservableList$2.set(ObservableList.java:253)
	at java.base/java.util.List.sort(List.java:510)
	at java.base/java.util.Collections.sort(Collections.java:179)
