dev build 200506231800 JDK 5.0 update 4 I have an old web project from an older Netbeans 4.2 daily build (a few weeks ago). When I do File -> Open Project -> Select old project directory with the mouse, the attached exception is thrown. This seems to be a genuine bug not having to do with the fact I am using an older userdir. You be the judge :)
Created attachment 22878 [details] stack-trace
Upgrading to P1. I used a fresh userdir, created a new project. This worked fine. Then I restarted Netbeans and tried reopening this project and found it to be impossible.
I can't reproduce with 4.1 project. Does your project use external sources, i.e. source folders are located outside of the project folder? (created as Project with Existing Sources)
It seems like a duplicate of issue #60371, the same stack trace. *** This issue has been marked as a duplicate of 60371 ***
