Occasional EOFException when reading cached file

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Try to load lots of previously cached images in a ListView by quickly 
scrolling back and forth
2. Some images will fail to load

What is the expected output? What do you see instead?
Files (in this case bitmaps) should be read from cache, but instead we get an 
EOFException like the following:

It appears that the same problem occurs with not just bitmaps but also any 
other file.

I believe this is an Android issue.  I've hit the same problem with base 4.0.4 
and am guessing it's an HTTP keep-alive issue as it only happens on the second 
of back to back HttpsURLConnection use.  I verified that I'm reading the whole 
stream before disconnecting/returning to the pool, so will just disable 
http.keepAlive for now.  It's reproducible, but only happens about 25% of the 
time.

Confirmed, same here. Adding a "Connection: Close" header solves the problem.

Adding the following line
System.setProperty("http.keepAlive", "false");

just before creating the instance of the UrlConntion:
conn = (HttpURLConnection) url.openConnection();

Disables the keepalive via de client (android App). And also prevents the bug.
