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

             Summary: ClassNotFoundException with IvyDE-Libraries ni WindowGUI-Builder
                 Key: IVYDE-337
                 URL: https://issues.apache.org/jira/browse/IVYDE-337
             Project: IvyDE
          Issue Type: Bug
          Components: classpath container
    Affects Versions: 2.2.0.beta1
         Environment: Windows 7, 64-Bit, JRE 1.7.0_08, Eclipse Juno 4.2.1
            Reporter: Alexander Gräf


Dear IvyDE-Team,

we habe got an issue in an Eclipseproject that is using the IVYDE-Classpathcontainer for dependencymanagement.
In the project we are designing some Swing based forms and use the WindowBuilder integrated
in Eclipse Juno 4.2.1 for this purpose.

Whenever we try to open a Form in the Designview of the Windowbuilder, a ClassLoaderException
is thrown, so the designview can not be used. The same form is rendered correctly, if we put
the dependant libraries in the Buildpath of eclipse without the IVYDE-Classpathcontainer.

We have attached the Stacktrace of the exception below:

Unable to load 'super' class
WindowBuilder was unable to load class ibr.grund.helper.gui.dialog.JIbrStandardDialog that
is used as super class for your form. This usually happens when: 

Compilation unit has compilation problems. 
Super class is in project, but automatic build is turned off.
