JAVA/SAX - Loss of characters using XML Parser

I'm using SAX Parser to parse the XML file of RSS feeds on an Android App and sometimes the parsing of the pubDate of an item isn't completed (incomplete characters).

Ex:

Actual PubDate Thu, 02 Apr 2015 12:23:41 +0000

PubDate Result of the parse: Thu,

Here is the code that I'm using in the parser handler:

public void startElement(String uri, String localName, String qName, Attributes attributes) throws SAXException {
        if ("item".equalsIgnoreCase(localName)) {
            currentItem = new RssItem(url);
        } else if ("title".equalsIgnoreCase(localName)) {
            parsingTitle = true;
        } else if ("link".equalsIgnoreCase(localName)) {
            parsingLink = true;
        } else if ("pubDate".equalsIgnoreCase(localName)) {
            parsingDate = true;
        }
    }

    @Override
    public void endElement(String uri, String localName, String qName) throws SAXException {
        if ("item".equalsIgnoreCase(localName)) {
            rssItems.add(currentItem);
            currentItem = null;
        } else if ("title".equalsIgnoreCase(localName)) {
            parsingTitle = false;
        } else if ("link".equalsIgnoreCase(localName)) {
            parsingLink = false;
        } else if ("pubDate".equalsIgnoreCase(localName)) {
            parsingDate = false;
        }
    }

    @Override
    public void characters(char[] ch, int start, int length) throws SAXException {
        if (parsingTitle) {
            if (currentItem != null) {
                currentItem.setTitle(new String(ch, start, length));
                parsingTitle = false;
            }
        } else if (parsingLink) {
            if (currentItem != null) {
                currentItem.setLink(new String(ch, start, length));
                parsingLink = false;
            }
        } else if (parsingDate) {
            if (currentItem != null) {
                currentItem.setDate(new String(ch, start, length));
                parsingDate = false;
            }
        }
    }

The loss of characters is pretty random, it happens in different XML items every time I run the app.
