Symptom

You have configured the File Adapter in your scenario with following options set in configuration:
1.Files are to be archived (with or without timestamp) after processing.
2.Local file system (and not the FTP server) is to be used for the files thus archived.
3.Content conversion would take place.
However, a java.lang.NegativeArrayException occurs, and the archiving of the file fails.
Other terms

File adapter, FTP Adapter, Archiving, java.lang.NegativeArrayException, Local file system
Reason and Prerequisites

This issue occured due to a programmatic error only when you chose to archive the file in local system, not on the FTP server. The NegativeArrayException was thrown only in the case of a few FTP servers that do not return the file size along with file name when the FTP adapter issues the commmand for listing of files in a specific directory.
Solution

The issue has been solved by changes in the code. The archives and the support package stack guide can be found on the SAP Service Marketplace as described in SAP Note 952402.
