NPE when getting transform from MapViewport
-------------------------------------------
Key: GEOT-3791
URL: https://jira.codehaus.org/browse/GEOT-3791
Project: GeoTools
Issue Type: Bug
Components: swing
Affects Versions: 8.0-M1
Reporter: Michael Bedward
Assignee: Michael Bedward
Fix For: 8.0-M2
Reported on the user list and confirmed by Jody. I haven't been able to
reproduce it on my macbook so it may be related to speed of the system...
possibly a concurrency bug introduced in the last few days of swing hacking.
