NB4.1 + JBuilder importer

Steps to reproduce:
- run JBuilder
- create Project with libraries:
   - add Xalan from JBuilder Libraries
   - add some Application from existing Projects
   - add openide.jar, core.jar from archives
- with multiple sources (Source_1 and Source_2)
- define your own JDK
- run NB4.1 with importer
- try to import the project
- when you specify the directory where the project is located, the wizard asks
you to write JBuilder Installation directory - uncheck the checkbox (because of
issue 60154)
- push Finish button
-> dialog reporting progress of import just blink and import finished without
any warnings/exceptions/failures/logs ! ->>>> means nothing has been imported

I've found in the log file next two lines :

[WARNING]: 20050616_163044 CEST -
org.netbeans.modules.projectimport.j2seimport.AbstractProject.addWarning(): 
user library "Xalan" defined in project "P60154)roject_complex" could not be
resolved.
[WARNING]: 20050616_163057 CEST -
org.netbeans.modules.projectimport.j2seimport.ImportUtils.importProjectWithoutDependencies():
Project already exists: local_export/Work/ProjectsImporter/JB_projects_in_NB


The first one belongs to the problem reported in issue 60154, the second one I
really don't understand. The directory from the log has not been created until I
hit the FInish button (I checked it three times), then the exmpty directory with
this name is created and nothing is imported...

Am I doing something wrong ?
