Senduran updated SYNAPSE-1014:
------------------------------
Attachment: HelloProxy.xml
Hi Isuru
Here I am attaching the proxy configuration I used[^HelloProxy.xml]. When I get
this NPE. But surprisingly I am not getting this exception with the latest
trunk. So I did the followings.
* In the latest trunk, reduced the http core and httpcore and http-client
version to older version i.e 4.3, 4.3.1. But still couldn't reproduce the
issue.
* So I reverted to an older synapse revision 1745801 (this is the revision just
before the http core and http-clinet version upgrade). With this revision, I
got the NPE as well as the build failure error which is reported in
SYNAPSE-1015.
* On top of revision 1745801, I applied the diff mentioned in SYNAPSE-1015 and
eliminated the build error. And I got the NPE.
According to above behavior I believe the NPE is been fixed by a recent fix.
