Hello

Can you dig more into the cause of the error ? If you're using version 0.4.4, you are using graphviz 8000, which is http://grepcode.com/file/[email protected]$plantuml@8000@net$sourceforge$plantuml$svek$image$EntityImageClass.java

The code you refer to is
'''
this.shield = version.useShield() && entity.hasNearDecoration() ? 16 : 0;
'''
which points to a null entity or a null version... Really strange, I can't work it out further.

If you have the UML Script (between those @startuml and @enduml), you can try it out on http://www.plantuml.com/plantuml/form - does the script cause the error?
