In debug "Variables" view, I want to create text output for each element of a list, one per line instead of comma separated. So I select the list and edit the detail formatter. The detail formatter is for a ArrayList. I tried this: this.stream() .map( i -> i.toString()) .collect(java.util.stream.Collectors.joining("\n")) Detail formatter error: The method stream() is undefined for the type ArrayList<E> I suspected the stream() as default method being the problem. So I tried to inline the impl: java.util.stream.StreamSupport.stream(this.spliterator(), false) .map( i -> i.toString()) .collect(java.util.stream.Collectors.joining("\n")) Detail formatter error: The method spliterator() from the type ArrayList<E> refers to the missing type Spliterator I am not sure if this is my lack of knowledge how to use this. Or if this is a bug?
This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet. If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant. -- The automated Eclipse Genie.
