-----------------------------------

             Summary: Large Project Explorer tree causes editor input to lag
                 Key: JBIDE-26529
                 URL: https://issues.jboss.org/browse/JBIDE-26529
             Project: Tools (JBoss Tools)
          Issue Type: Bug
          Components: jst
    Affects Versions: 4.9.0.Final
         Environment: Java 11, Eclipse 2019.03 JEE, Windows 7

            Reporter: Jesper Skov
         Attachments: eclipse-bug-jboss.zip

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.
