Description Mikel Waxler

Build Identifier: 20100218-1602 

When creating a new project from existing source, it can take exceptionally long to search for source tree roots. Our source code has only 2 roots and ~150,000 files, but eclipse finds many source roots. because our tree is so large, it takes upwards of 10-15 minutes to find all these folders. I then needs to remove almost all of them. 

I am happy to provide statistics on the source tree, but cannot give out any information about the contained code.

There are a couple of extra source roots that are in the tree for side projects/ alpha code. Some of which are inside the larger roots.

Reproducible: Always

Steps to Reproduce:
1. Create Java Project
2. Select a large existing source tree.
3. Hit next
4. wait 10-15 minutes.

Please create some stack dumps while it's searching the source and attach them here.

I assume that there is a way to do this from the command line, can you shoot me some instructions? The Eclipse ui is totally locked up during this process. 

Something as simple as an option to skip the search would be fine with me.

This should help: http://wiki.eclipse.org/How_to_report_a_deadlock

We'd need more info to do anything here.
