LexicalPreservingPrinter throws UnsupportedOperationException when removing comments

[JustinKissling]

Hi,
Whenever I try to delete a line or block comment while using the LexicalPreservingPrinter, I get an UnsupportedOperationException. Javadoc comments seem to work fine.

Example:

        FileInputStream in = new FileInputStream(path);
        CompilationUnit compilationUnit = LexicalPreservingPrinter.setup(JavaParser.parse(in));
		
		List<Comment> comments = compilationUnit.getAllContainedComments();
		
		for (Comment comment : comments) {
			// throws UnsupportedOperationException unless it's a Javadoc comment
			comment.remove();
		}
