Arūnas Bendoraitis updated HTTPCORE-339:
----------------------------------------

    Description: 
    ContentType(
            final String mimeType,
            final NameValuePair[] params) throws UnsupportedCharsetException {
        this.mimeType = mimeType;
        this.params = params;
        final String s = getParameter("charset");
        this.charset = s != null ? Charset.forName(s) : null;
    }

It only checks for null, but should check for empty as well.

Last line should be replaced with:
 this.charset = !TextUtils.isBlank(s) ? Charset.forName(s) : null;


In create method as far as I remember there was the same bug earlier, but now 
it's fixed and is like this:

    public static ContentType create(
            final String mimeType, final String charset) throws 
UnsupportedCharsetException {
        return create(mimeType, !TextUtils.isBlank(charset) ? 
Charset.forName(charset) : null);
    }


Some hosts may have empty string in the charset and then 
IllegalArgumentException happens in Charset.forName(..).

        this.params = params;
