HTTP file handler doesn't close files

[GoogleCodeExporter]

Function writeFile in DefaultServlet.java leaves file stream open.

Recommend:
Close FileInputStream in DefaultServlet

FileInputStream fis = new FileInputStream(file);    
FileChannel fileChannel = fis.getChannel();
mapedFile.data = fileChannel.map(FileChannel.MapMode.READ_ONLY, 0, 
fileChannel.size());
fileChannel.close();
fis.close();
