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 For example: when a @throws is no longer valid, a quick fix to remove the comment would be great.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.

for (int i= 0; i < nTags; i++) {
			TagElement curr= (TagElement) tags.get(i);
			if (name.equals(curr.getTagName())) {
				if (arg != null) {
					String argument= getArgument(curr);
					if (arg.equals(argument)) {
						return curr;
					}
				} else {
					return curr;
				}
			}
