Aklakan opened a new issue, #1384:
URL: https://github.com/apache/jena/issues/1384
### Version
4.6.0-SNAPSHOT
### What happened?
When trying to activate one of my sparql benchmark processors I noticed that
the following line no longer works with a remote HTTP connection:
```java
try(QueryExecution qe = conn.query(query)) {
qe.setTimeout(connectionTimeoutForRetrieval,
executionTimeoutForRetrieval);
}
```
Initial/connect timeout may be a bit of a niche feature but when working
with third-party endpoints it can be a very handy thing - I once had a case
where a downed sparql endpoint would hold the connection for several minutes;
that's why eventually I made use of this Jena feature.
In my case, the line above ends up at QueryExecHTTPBuilder which raises a
`UnsupportedOperationException`:
```java
class QueryExecHTTPBuilder {
@Override
public QueryExecHTTPBuilder initialTimeout(long timeout, TimeUnit
timeUnit) {
throw new UnsupportedOperationException();
}
}
```
Attempting to using the more recent `conn.newQuery().setTimeout()` API also
does not work, because it lacks lacks a method to set the initial (aka connect)
timeout alltogether.
According to [stack
overflow](https://stackoverflow.com/questions/3000214/java-http-client-request-with-defined-timeout)
the Java http client actually supports this feature so it seems it's just a
matter of wiring this up again:
```java
// set the connection timeout value to 30 seconds (30000 milliseconds)
final HttpParams httpParams = new BasicHttpParams();
HttpConnectionParams.setConnectionTimeout(httpParams, 30000);
client = new DefaultHttpClient(httpParams);
```
