Avoid creating a new coordinate operation factory for each scale computation in
RenderUtils
-------------------------------------------------------------------------------------------
Key: GEOT-973
URL: http://jira.codehaus.org/browse/GEOT-973
Project: GeoTools
Issue Type: Improvement
Components: core render
Affects Versions: 2.3.M0, 2.2.0, 2.2.1, 2.3
Reporter: Andrea Aime
Assigned To: Jesse Eichar
Fix For: 2.2.1, 2.3
Gathering a new coordinate operation factory for each scale computation
triggers some very
nasty OOMs in geoserver because for each call to getCoordinateOperationFactory
apparently
8 factories come into existance and get deleted only after 30 minutes, populi
Here is the patch:
