Bug 66923 [typing]Can delete word (Ctrl-Backspace) on read only file
When you open read-only java file, all editing functions are disabled except deleting with Ctrl-Backspace and Ctrl-Del, then it is imposible to save this file. On simple text file it works ok - it blocks all edditing functions (including Ctrl-Backspace). I am using build 200406111814
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/javaeditor/CompilationUnitEditor.java
return unit.getElementAt(offset);
				} else if (unit.isConsistent())
					return unit.getElementAt(offset);
					
			} catch (JavaModelException x) {
				if (!x.isDoesNotExist())
				JavaPlugin.log(x.getStatus());
				
			}
		}
		
		return null;
	}
