                 URL: https://issues.jboss.org/browse/JBIDE-26548
             Project: Tools (JBoss Tools)

    Affects Versions: 4.10.0.AM1
         Environment: Linux with Eclipse 2018-12
            Reporter: Thomas Zauner


Renaming of inner class java variables leads to an Nullpointer in JSFRenameFieldParticipant. The second rename is working, since the JSFRenameFieldParticipant is removed due to the exception.
