Nick Boldt commented on JBDS-4149:
----------------------------------

New log shows constraint violations caused by javax.servlet-api 3.1.0 and javax.servlet 3.1.0.v201410161800, then this:

{code}org.osgi.framework.BundleException: Unable to acquire the state change lock for the module: osgi.identity; type="osgi.bundle"; version:Version="1.7.1.20161026-1743"; osgi.identity="org.eclipse.m2e.jdt"; singleton:="true" [id=635] STARTED [STARTED]
{code}

So... this is no longer anything to do with slf4j or lucene. 

Lukas, please log to a separate file for each startup of Eclipse -- it will make separating your errors based on what you are doing in Eclipse easier.

Here's how I run devstudio from rpm, in a unique workspace each time and logging to a different log file each time:

{code}
rm -fr ~/.eclipse
scl enable rh-eclipse46 bash
cd /opt/rh/rh-eclipse46/root/usr/lib64/eclipse/
./eclipse -consolelog -console -debug -data /tmp/wksp-`date +%Y%m%d-%H%M`| tee /tmp/rh-eclipse46-devstudio10.2.log.`date +%Y%m%d-%H%M`.txt
{code}
