Duplicate code in o.c.opibuilder.* #1650
Description
Some of the code in o.c.opibuilder.editor is reproduced in o.c.opibuilder.tools.
ResourceSelectionGroup.java differs only by a null-check and WorkspaceResourceContentProvider.java is identical.
Are both sets of code still required for any reason, or were they left while moving functionality between different plugins and packages? Which is the 'correct' location?
I stumbled on these two while fixing Checkstyle warnings. I'd be surprised if they're the only ones.
Has there ever been a systematic review of the code looking for duplicated classes?
