Hi,
it looks that test class was committed by Jody following up a pull request
from IGN:
https://github.com/geotools/geotools/commits/master/modules/library/render/src/test/java/org/geotools/renderer/lite/LetterConflictTest.java
Could be the usual thing of manually registering and using a cross platform
font like it's done in other tests, e.g:
https://github.com/geotools/geotools/blob/master/modules/library/render/src/test/java/org/geotools/renderer/lite/ScreenMapShapefileTest.java#L96
It's weird that the build sometimes passes, and sometimes does not?
Cheers
Andrea
