Sridhar Ratna commented on AXIS2-5301:
--------------------------------------
I got the same error while working with axis2 1.6.1 and axis2 1.6.2. This stack
is generated from Axiom 1.2.12.
Given a look at the BAAOutputStream.java and it is storing the 4K size of
buffers to arraylist which is causing the problem.
the following is get called repeated ly.
private void addBuffer() {
currBuffer = new byte[BUFFER_SIZE];
data.add(currBuffer);
index = 0;
}
I didn't understand when the Inputstream is available why populating into Byte[]

> I am trying to upload and download large binary files with axis2 using MTOM.
> I am able to upload upto 2GB file without any memory issue either at server
> side or client side. But when downloading file from server to client, client
> is getting out of memory, though the server is sending a stream.
> When the response received at client side, javax.activation.Datahandler is
> embedded in the response which is a pointer to InputStream. Ideallly it
> should not give out of memory. And this is the same mechanism while
> uploading, and there is no problem at that end.
> Seems to be a bug at client side handling of large documents in response
> stream.
