Login failed: loading constraint violation error when connecting to Jazz project from Eclipse 6.0.5 plugin

Peter Moraza (481924) | asked Jan 04 '19, 3:17 p.m.

I installed the RTC Eclipse plugin "" in IBM Integration Toolkit After entering the Jazz url and login credentials in a Jazz Administration perspective to log into our Jazz 6.0.5 repository, the connection attempt fails immediately with the following error:

Login failed: loading constraint violation when resolving method "org/apache/http/client/protocol/HttpClientContext.setCookieStore(Lorg/apache/http/client/CookieStore;)V" : loader "org/eclipse/osgi/internal/baseadaptor/DefaultClassLoader@b120c135" of class "com/ibm/team/repository/transport/client/RemoteTeamServer" and loader "org/eclipse/osgi/internal/baseadaptor/DefaultClassLoader@dee12c56" of class "org/apache/http/client/protocol/HttpClientContext" have different types for the method signature

Any ideas how I can overcome this error? TIA

I have the same issue using RTC Client (6.0.5) and Rational Software Architect v9.7, did you manage to solve the issue?

I don't know the answer... but it appears there are other questions on this forum related to this:

I am still having the same issue. I will keep working on it. 

Kevin Ramer commented Jan 16 '19, 3:49 p.m.
Hopefully it's obvious that the run-time is finding 2 definitions for DefaultClassLoader.  The question is Why?.    One suggestion might be to add
to the eclipse.ini and capture the output to a file [ requires starting up in a shell, of course ]

After upgrading my environment, I have the same issue with RTC 6.0.6 shell-shared with IDZ 14.1.6. Is there a solution available?

Dennis, ask your own question and maybe check with support. Check the Eclipse versions that are supported. Just a thought.

 Hi Everyone,

I'll share how I was able to finally overcome the exception, although I can only speculate as to the cause. I backed-up my work then deleted my installation of IBM Integration Toolkit which I may have installed using a non-admin id. I then installed version by right-clicking the .exe file and selecting "Run as administrator" and specifying an admin/elevated account. After installation completed I installed the "" plugin. I was able log onto RTC from the Jazz Administration perspective with no issues. I'm guessing that installing the Toolkit with the elevated id made the difference. I hope this helps.

Could you try starting eclipse from the command line with -clean option? For instance
$> eclipse -clean

 I have tried the -clean option, but the same behaviour. I upgraded from 6.0.2 to 6.0.6.
