Description

Rest route returns Response with http Status code 500 Internal Server Error and expected response headers/body when response has Last-Modified or Header-expires in header as string.

I found the issue in below code it try to convert string Wed, 31 Dec 1969 18:00:00 CS to Date and it fails. Is it posible to convert String Date without knowing Date format?

DefaultRestletBinding
=======================

if (header.equalsIgnoreCase(HeaderConstants.HEADER_LAST_MODIFIED)) {
if (value instanceof Calendar)

{ message.getEntity().setModificationDate(((Calendar) value).getTime()); }

else if (value instanceof Date)

{ message.getEntity().setModificationDate((Date) value); }

else

{ Date date = exchange.getContext().getTypeConverter().mandatoryConvertTo(Date.class, value); // Here it try to convert String to Date it throws No type converter available to convert from type: java.lang.String to the required type: java.util.Date with value Wed, 31 Dec 1969 18:00:00 CS message.getEntity().setModificationDate(date); }

}
