-------------------------------------------
Summary: MainClientExec.prepare() throws
java.lang.IndexOutOfBoundsException: Index: 0, Size: -1
Key: HTTPASYNC-151
URL: https://issues.apache.org/jira/browse/HTTPASYNC-151
Project: HttpComponents HttpAsyncClient
Issue Type: Bug
Affects Versions: 4.1.4
Reporter: saroja nidadavolu
Fix For: 4.1.5
There is a server which connects to third party server to fetch valid HTTP
response.
Configured a thread pool of size 2 and trying to get the response through
future get and then facing IndexOutOfBoundsException: Index: 0, Size: -1. Issue
is seen *intermittently*.
{code:java}
// My lines of code where issue is seen
public Object processRequest() throws Exception {
..
..
Future<HttpResponse> future = httpclient.execute(httpReq, context, null);
httpResponse = future.get();
..
..
}{code}
As a java developer, I have never seen IIndexOutOfBoundsException with size of
-1, so only thing I can guess is that the List is not being used in thread safe
manner(redirectLocations in MainClientExec.java), corrupting the list.
