Description Thomas Watson CLA 2010-11-16 08:23:45 EST

Cocoa 32-bit build.

Steps to reproduce:
1) start eclipse without specifying -data <workspace>
2) the workspace chooser dialog is shown.
3) click on browse button to bring up finder.
4) click around in finder a bit and notice the UI hangs

On my system the UI thread is spinning the CPU and stuck in org.eclipse.swt.internal.cocoa.OS.objc_msgSend

Comment 1 Scott Kovatch CLA 2010-11-16 11:27:26 EST 
If you can reproduce this, open up a Terminal window and run sample on the process:

%  sample <PID of hung process> 2 20

Then, attach the dump to the bug. This is almost always a bad remote mount point.

Comment 4 Thomas Watson CLA 2010-11-16 11:45:10 EST 
The first dump I caused by click the drop down in the workspace chooser instead of using the Browse button.

The second dump I caused by clicking the Browse button and navigating the finder a bit.
Comment 5 Thomas Watson CLA 2010-11-16 11:54:15 EST 
I have tried to reproduce this on 3.6 with the same machine but have not been successful.
Comment 6 Scott Kovatch CLA 2010-11-16 12:19:30 EST 
I'll see what I can do to reproduce it. Both sample traces show we're stuck inside AppKit and not the SWT.
Comment 7 Thomas Watson CLA 2010-11-17 13:35:37 EST 
I should have mentioned this before.  I am using 10.5.8 Mac OS X.  I am mentioning this because I saw you post a note about some conditional check for 10.5 vs 10.6 to the releng list.
Comment 8 Eclipse Genie CLA 2018-11-30 13:24:50 EST 
This bug hasn't had any activity in quite some time. Maybe the problem got resolved, was a duplicate of something else, or became less pressing for some reason - or maybe it's still relevant but just hasn't been looked at yet.

If you have further information on the current state of the bug, please add it. The information can be, for example, that the problem still occurs, that you still want the feature, that more information is needed, or that the bug is (for whatever reason) no longer relevant.

Comment 9 Lakshmi P Shanmugam CLA 2018-12-21 01:46:46 EST 
This was reported on Mac 10.5 and Eclipse 3.7. 
Closing it as I'm unable to reproduce this with Eclipse 4.10 and macOS 10.14. Also, there are no reports of Directory Dialog hang for a long time.
