Hi Nick,

I tested installation of stuff from central as you described. I am not finished yet, but here is what I found.

-install latest integration stack bits from IS
 -JBoss Fule Development - OK
 -JBoss Business P. and Rules D. - OK
 -JBoss Integration and SOA D. - OK
 -JBoss Data Virtualization D. (IS early acess) 
   -there is problem with slf4j
   -IS contains Teiid 11.0.1.CR1-v20170117-222 which should be fixed
   -there are error like this:

{code}
!MESSAGE Problems occurred when invoking code from plug-in: "org.eclipse.equinox.preferences".
!STACK 0
java.lang.LinkageError: loader constraint violation: when resolving method 
"org.slf4j.impl.StaticLoggerBinder.getLoggerFactory()Lorg/slf4j/ILoggerFactory;" the class loader 
(instance of org/eclipse/osgi/internal/loader/EquinoxClassLoader) of the current class, 
org/slf4j/LoggerFactory, and the class loader 
(instance of org/eclipse/osgi/internal/loader/EquinoxClassLoader) for the method's defining class, 
org/slf4j/impl/StaticLoggerBinder, have different 
Class objects for the type org/slf4j/ILoggerFactory 
used in the signature{code}

-install everything from Central (including PMD and Findbugs, and early access stuff. NOTE: newer versions of the Integration Stack connectors should already be installed from the step above)
 -I installed everything using Central-Software/update, *no remediation action* was needed.
 -Eclipse started but with many errors. So I have to find out which feature causes the problem.{quote}

loader constraint violation == two different versions of slf4j in the installed plugins
check in :~/.eclipse/org.eclipse.platform_283378046_linux_gtk_x86_64 vs. in /opt/rh/

Problem appears to be in *org.slf4j.impl.StaticLoggerBinder.getLoggerFactory()Lorg/slf4j/ILoggerFactory*. {quote}

{code}
cd ~/.eclipse/org.eclipse.platform_283378046_linux_gtk_x86_64
find . -iname *slf4j*
./configuration/org.eclipse.osgi/1293/0/.cp/lib/slf4j-api-1.6.1.jar
{code}
The output for /opt/rh/ is quite long but I can say that it contains slf4j.api_1.7.4.jar

So, we may have a conflict between slf4j and slf4j-api, which both use the same bundle names, but expose packages differently.

Unclear which IS project is causing this problem as I thought we'd fixed both SY and TD already.

I tried to install Jboss Data Virtualization Developement from [IS discovery site|http://download.jboss.org/jbosstools/neon/integration/updates/integration-stack/discovery/4.4.1.CR1/] again.

Whole log:  
[^rh-eclipse46-devstudio10.3-0.20170206.0203.el7.log.Jboss_Data_Virtualization_Developement_form_IS_repo_strict.txt] 

Slf4j files in ~/.eclipse/org.eclipse.platform_283378046_linux_gtk_x86_64/
 [^home_eclipse.txt] 

Slf4j files in /opt/rh/
 [^opt_rh.txt] 

The problem is caused by Teiid Designer and Teiid Designer Runtime. 
Teiid DataTools Connectivity and Teiid Runtime Clients don't cause problem.

IS repository contains SwitchYard  2.3.0.CR1-v20170120-1347-B20 which works properly.
