Just an update on unresolved bundles. I looked at rh-eclipse46-devstudio-10.2-0.20161103.0650.el7.x86_64.rpm and the only ones are:
ch.qos.logback.slf4j
org.slf4j.impl.log4j12{quote}

Both of those bundles declare

{code}Fragment-Host: org.slf4j.api;bundle-version="[1.7.2,1.7.3)"{code}

And since we're now using slf4j.api_1.7.4.jar, which has in its MANIFEST.MF:

{code}
Export-Package: org.slf4j;version=1.7.4, org.slf4j.spi;version=1.7.4, 
 org.slf4j.helpers;version=1.7.4
Import-Package: org.slf4j.impl;version=1.6.0;resolution:=optional
Bundle-SymbolicName: slf4j.api
{code}

I suspect we need to find newer versions of those that can use slf4j 1.7.4 instead of 1.7.2.

  was:
Tested:
 * rh-eclipse46-devstudio-10.2-0.20161004.2205.el7.x86_64.rpm
 * rh-eclipse46 Beta (http://download-node-02.eng.bos.redhat.com/rel-eng/RHSCL-2.3-RHEL-7-Beta-1.0/compose/Server/x86_64/os/)

rh-eclipse46 has its own unresolved bundles (https://bugzilla.redhat.com/show_bug.cgi?id=1381820). But when you add rh-eclipse46-devstudio, the number of unresolved symbols increases quite dramatically and initial start up times also get worse. (I guess that the two problems can be connected so I file them together but feel free to split them if I'm mistaken).

I'm attaching "ss -s INSTALLED" and workspace logs for several scenarios:
 * "min" in the name means minimal install rh-eclipse46-devstudio
 * "mid" is for "yum install rh-eclipse46 rh-eclipse46-devstudio"
 * "max" is for "yum install 'rh-eclipse46*'" - all the available RPMs, including devstudio

As for start up times, it looks like devstudio adds ~80s for one particular machine (Xeon with 16 cores 2.40GHz, 16 GB RAM). For example:
initial start of rh-eclipse46: 40s
same as above with rh-eclipse46-devstudio: 120s
initial start of rh-eclipse46* except devstudio: 50s
same as above with rh-eclipse46-devstudio: 140s

Roland Grunberg managed to improve initial start up times in rh-eclise46 a few weeks ago (https://bugzilla.redhat.com/show_bug.cgi?id=1362178#c17). I don't know it it helps here but I'm linking it anyway...
