Getting NegativeArraySizeException while transferring file from MPA3.0 to MPA 7.10
Other terms

NegativeArraySizeException, Marketplace Adapter

Reason and Prerequisites

If the content type is set to “application/www-form-urlencoded”, then the servlet can access this content either by calling either getInputStream() method or getParameter() method (but not both) on the HTTP request. Until SP16, we did not use getParameter() method in the messaging servlet. But with SP18 onwards, and future releases (710), we introduced getParameter() method before calling getInputStream() for some additional features released.
Due to this, InputStream is becoming empty in latest releases and this is the cause of NegativeArraySizeException.
This is issue with the JDK5; it has a bug which sets the message content
type always to application/x-www-form-urlencoded. See link for
