State diagrams do not work. I'm using Redmine with Jar files

Question

Hello,

I've installed the PlantUML plugin for Redmine and everything looks fine.

But I cannot make any State diagram to work. Examples:

[*] --> State1
State1 --> [*]
State1 : this is a string
State1 : this is another string

State1 -> State2
State2 --> [*]

(yes, I used the start and end tags)

The jar versions I've tested are:

plantuml-8059.jar

plantuml.1.2017.16.jar

This is the way I use it:

/usr/bin/java -Djava.io.tmpdir=/var/tmp -Djava.awt.headless=true -jar /var/www/redmine/plugins/plantuml/bin/20171003-plantuml.1.2017.16.jar ${@}

As I said before, every other diagram works fine, but not State diagrams.

Thanks for your help

So this is not working:
@startuml
[*] --> State1
@enduml

And this is working:
@startuml
class Foo
@enduml

Right ?

No. Fail too.
Activity diagram, Trees and Gantt works (the types I've tested successfully up to this point)

Ok, this means there is an issue with your GraphViz installation.
See http://plantuml.com/graphviz-dot
Can you try the following diagram:
@startuml
testdot
@enduml
Thanks!

Graphviz installed. Now, some test works, some test fails, because uppercase letters. Example:

This fails:
[*] --> State1
State1 --> [*]
State1 : this is a string
State1 : this is another string

State1 -> State2
State2 --> [*]

This works:
[*] --> state1
State1 --> [*]
State1 : this is a string
State1 : this is another string

State1 -> State2
State2 --> [*]

(the difference is in the first line:
[*] --> State1
and
[*] --> state1

We've discovered that there is a cache issue here.
The fail examples works as soon as we change from png to svg.
