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

                 Key: JBIDE-3278
                 URL: https://jira.jboss.org/jira/browse/JBIDE-3278
             Project: Tools (JBoss Tools)
          Issue Type: Bug
    Affects Versions: 3.0.0.cr1
         Environment: eclipse.buildId=M20080911-1700
java.version=1.6.0_10
java.vendor=Sun Microsystems Inc.
BootLoader constants: OS=linux, ARCH=x86, WS=gtk, NL=en_DK
Command-line arguments:  -os linux -ws gtk -arch x86 -clean
            Reporter: arne anka

besides the jboss server i got several servers configured (tomcats), which appear in the
"jboss server view" as well.
when expanding one of these nodes (not the jboss one) i keep getting npes, stacktrace
below.
additionally there's an empty line shown, probably marking the deployed webapp.
