Description Xiaonan Jiang CLA 2010-06-09 11:13:05 EDT 
Build Identifier: 3.6RC3

From the javacore, looks like the time is spent on traversing the file system. this is unnecessary since the folder and filename can be retrieved from the import wizard.

Reproducible: Always

Steps to Reproduce:
1. Create a project
2. Right-click a folder and select "Import" menuitem
3. Select "General/File System" and click the "Next" button.
4. Enter "C:\" in the "From directory" folder and press Enter key
5. Select the folder and select a file on the right listbox
6. Click the "Finish" button.

eclipse hangs.

It is not actually a hang, but it does take a long time. I agree it shouldn't need to recursively populate the entire file system model at this point.

This seems to be a dup of bug 312959
