Bug 24799 Java structure compare fails too many times
Using 1009, when I synchronize with the cvs server and I compare my outgoing changes with the repository contents, I get too many times "Java Structure Compare (Can't Compare Structures)". This didn't happen in the past. I don't know what changed, but this is frustrating and make the whole synchronization process very difficult to use. It is not always the same files which are failing. I didn't get anything in a .log file.
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/compare/JavaStructureCreator.java
DiffNode d= (DiffNode) differencer.findDifferences(true, null, root, i.fAncestor, i.fLeft, i.fRight);
				if (d != null) {
					d.setDontExpand(true);
					Iterator it2= i.fChildren.iterator();
					while (it2.hasNext()) {
						IDiffElement rd= (IDiffElement) it2.next();
						root.removeToRoot(rd);
						d.add(rd);
					}
				}
			}
		}
