The default open tip/head arrow in activity diagrams are changing to closed-filled ones with strictuml skin parameter

Question

I always use skinparam style strictuml in my diagrams. In my Activity Diagrams (New Syntax), I tried nearly everything I could to change the arrow head (arrow tip) to be open (unfilled) instead of closed (filled). That bothered me lots, because AFAIK UML Activity Diagrams have transition arrows with open head (open tip).

Then the craziest thing happened: when I commented/removed the strictuml instruction... the arrow appeared just as it should in the default UML format! That pissed me off so much hahah

The reasons I'm writing this here are twofold: (1) help other users who could be struggling with that (especially trainers, professors etc.) and (2) report this as a bug that I believe must be simple to solve: when using  skinparam style strictuml, the open arrow (that is already default for PlantUML) should not turn into a closed filled arrow.

Just reinforcing: I am using the PlantUML Activity Diagram's New Syntax.

Hello M.,

Thanks for your report.

I just open this wanted feature for that:

Hello M.

Just to add some ref.:

• Could you cite some references that mention what UML strict mode should be?

Regards,
Th.

Sure! I'm happy to do it :)

UML v2.5.1 Specification, Section 15.2.4 - Notation (Figure 15.5).
It is also the reference I'm using for other comments I'm making here. :)
