> We use JBoss Tools with Eclipse JEE distribution.
> When Projetc Explorer contains a large tree (small elevator), performance of the java editor gets really bad with frequent lags.
> I have first reported it as a problem against native Eclipse (https://bugs.eclipse.org/bugs/show_bug.cgi?id=543678) but it turns out the problem can only be reproduced when the feature 'org.jboss.tools.jst.feature.feature.group' is installed.
