Does not render { } markup correctly

[lonmiller]

PlantUML Class Diagram documentation states that {} may be used to show a many relationship as so:

Class25 }-- Class26 (see http://plantuml.com/class-diagram) shows Class 25 as many-side relationship to Class26.

When markup of this type is entered and plantuml-viewer is called to render, it reports an error and shows this markup as invalid.
