[Geotools-devel] [jira] (GEOT-4458) Rentrancy Bug in RubberSheetTransform

Wed, 01 May 2013 14:55:29 -0700

Issue Type: Bug Bug
Affects Versions: 8.0
Assignee: Andrea Aime
Attachments: bug.diff
Components: referencing
Created: 01/May/13 4:54 PM
Description:

Multiple threads calling RubberSheetTransform.trnasform() can result in the wrong transformation being applied due to reentrancy problems in the handling of previousTriangle in searchTriangle().

I have attached the change we applied in 8.0 as a diff. If you like I can try to prepare a pull request against trunk when I'm at home.

I can't easily produce a test case to demonstrate the problem since it involves multithreading.
