Missing fonts used in SLDs should be cached
-------------------------------------------

                 Key: GEOT-2820
                 URL: http://jira.codehaus.org/browse/GEOT-2820
             Project: GeoTools
          Issue Type: Improvement
          Components: core styling
    Affects Versions: 2.6.0
            Reporter: Stefan Alfons Krüger
             Fix For: 2.6.1


Imagine the SLD TextSymbolizer describes a font that doesn't exist on the 
computer. At the moment, GeoTools will look for that font every time it's 
used.. throwing a lot of exceptions while rendering and using the default font 
at the end. Throwing and catching these exceptions makes rendering pretty slow.

My proposal is:

Extend the FontCache to also cache "FontNotFound" states to avoid multiple, 
repeating FontNotFound exceptions while rendering.
