The exception is thrown due to a call to java.util.zip.ZipOutputStream.close() at com.atlassian.jira.action.admin.DataExport.execute(DataExport.java:209) .
According to Sun Java documentation (http://java.sun.com/j2se/1.4.2/docs/api/java/io/PrintWriter.html#close()) , the stream has already been closed by the previous call to java.io.PrintWriter.close() at line 207 .
The exception is not caught at this level (lines 210 or 213 , resp.) , so it appears on the screen .

The file is closed correctly by line 207 , so I assume the backup file can be used .
The call to .getResult() (l. 212) is not executed , so the backup task is not completed .

Possible solution : One could catch the exception on line immediately , on l. 210 .
