Bug 47315 Add quick fix for remove an unused @ Javadoc tag. [quick fix]
The 3.0.m5 Javadoc warnings are *great* and will improve our Javadocs. Could we hae quick fixes for the new warnings when possible. For example: when a @throws is no longer valid, a quick fix to remove the comment would be great. Version 3.0.m5.
org.eclipse.jdt.ui/ui/org/eclipse/jdt/internal/ui/text/correction/JavadocTagsSubProcessor.java
int tabWidth= CodeFormatterUtil.getTabWidth();
					IRegion region= document.getLineInformationOfOffset(insertPosition);
					
					String lineContent= document.get(region.getOffset(), region.getLength());
					String indentString= Strings.getIndentString(lineContent, tabWidth);
					String str= Strings.changeIndent(comment, 0, tabWidth, indentString, lineDelimiter);
					InsertEdit edit= new InsertEdit(insertPosition, str);
					rootEdit.addChild(edit); 
					if (comment.charAt(comment.length() - 1) != '\n') {
						rootEdit.addChild(new InsertEdit(insertPosition, lineDelimiter)); 
						rootEdit.addChild(new InsertEdit(insertPosition, indentString));
					}
				} catch (BadLocationException e) {
					throw new CoreException(JavaUIStatus.createError(IStatus.ERROR, e));
