20030129 create a jproject, a source folder s1 and a nested in it source folder s2 delete s1 open the 'new' wizard and try creating a source folder s1 the error message is very long and compilicated while it should be a simple warning saying 'You have a folder s1 - I will turn it into a source folder fo you' (and then it could automagically add excelusion filter so that s2 is still a source folder)
