Rich Content widget widget stops working due to mix matched SSL protocols

For an IBM Connections 5.5 customer I found that periodically the Rich Content widget (RTE) stops working showing “The page could not be created due to an error” like the image below.


The following exceptions are seen in the SystemOut.log and access.log.

[6/21/16 10:10:34:889 CEST] 00000282 ConnectContro W oauth2Callback Exception while handling OAuth2 callback (I/O error on POST request for “”:Server returned wrong cipher suite for session; nested exception is Server returned wrong cipher suite for session).

There was an interesting thread in the Socially Integrated blog which was along the same lines but not a match so I raised a PMR. The ever dependable Dave McCarthy and Kevin Holohan shed some light on what was happening.

“According to a chat I had with L3, this is a bug in the JVM. If a connection is established with TLS 1.0 to a specific host (like say then it caches the TLS cipher that was exchanged with the host so that it doesn’t have to do negotiate again. Now if another app in JVM tries to establish connections with TLS 1.2 to the same host ( the cached info is reused. This causes the problem. is requesting TLS 1.2 but cached connection in JVM is at TLS 1.0”

It seems that the RTE application is not honouring the protocol as detailed in the Quality of protection (QoP) settings in the ISC and is trying to connect using TLS 1.2. This has triggered Technote How to Force IBM Connections 5.5 CR1 to Use TLSv1.2.

Furthermore I was made aware of LO89164 which is an update to RTE so that it utilises the intraservice URLs for each of the connections components and is be able to direct the HTTP requests issued by RTE component to the appropriate internal endpoint URLs, as referenced in the LCC.xml.

LO89164 can only be applied to CR01 which the customer is not running yet. LO89164 will be included in CR02. This ifix is only available from IBM by logging a PMR, it’s not on Fix Central.

When I am given a maintenance window I need to do the following:

  1. WAS FP8
  2. CR01
  3. Apply LO89164 (included in 5.5 CR2)
  4. Change QoP settings

This should cover off this problem. CR01 also includes other identified bugs in RTE which I won’t go into here but it’s worth applying….
