OutOfMemory exception with Multi-Part Zero Copy

[volts]

Hello,
I'm trying to upload a big file with multipart/form-data request.

AsyncHttpClient.BoundRequestBuilder request =
asyncHttpClient.preparePost("http://postservice");
Part p1 = new FilePart(filename, new File(filename), type, "binary");
Part p2 = new StringPart("importantparam", "param");
request.addBodyPart(p1);
request.addBodyPart(p2);
try{

Future<Response> f = request.execute();
Response r = f.get();
}
and received Out of Memory exception.

Is there another way I should make multipart request?
I found out that someone has been already reported about this issue
https://issues.sonatype.org/browse/AHC-78
and it's marked as fixed in 1.6.4, but it's still reproduced on fresh
async-client-1.6.4 version .
Is there any patch available?

Salut,

try 1.7.0 SNAPSHOT, which contains the fix IIRC. Let me know if that is
not the case.

Thanks
