Anthony Communier commented on CXF-5763:
----------------------------------------
The allow chunk parameter of httpClientPolicy was set to false
There are different kind of classes that are set into this.wrappedStream :
1/ CachedOutputStream (l 411)
2/ Annonymous OutputStream (l 417)
3/ CacheAndWriteOutputStream (l432) (extending CachedOutputStream)
In close method only CachedOutputStream is considered :
l 396: if ((!this.chunking) && (this.wrappedStream != null))
{
CachedOutputStream out = (CachedOutputStream)this.wrappedStream;
It seems that the code is in the case 2/ => Annonymous OutputStream
There are not so much comments in code in order to understand what has to be
done.
Waht could be done :
1/ Only test if it's this.wrappedStream is an instance of CachedOutputStream
before doing job done in close method
2/ Be sure that this.wrappedStream is always of type :CachedOutputStream
Note that if close occurs during setupWrappedStream this.wrappedStream could
be of 2 types because there is no protection
