Describe the bug

I met a peculiar behavior while utilizing your wonderful functionality or rendering PlantUML diagrams.

For some reason, when I try to create an association between a class field and enum related to it, if said enum has a note attached to it’s member, the association isn’t there.

To Reproduce Steps to reproduce the behavior:

1. Go to https://app.diagrams.net/
2. Click on Arrange => Insert => Advanced => PlantUML
3. Insert the following PlantUML diagram:

@startuml

enum Foo {
    Bar
}

note left of Foo::Bar
    Buggy note
end note

class Buzz {
    foo: Foo
}

Buzz::foo --> Foo

@enduml

1. See the error

Expected behavior

As displayed by plantuml.com, the association needs to be visibly rendered.

Additional context

I suspect some dependency update are due on your server side, since I have at the moment no means to confirm how standalone installation behaves but considering that official implementation does work okay that seems to be precisely the case.

The issue is fixed. We are now on version 1.2022.6 of PlantUml

This seems to be the result of regression, according to https://github.com/plantuml/plantuml/issues/983 But still, it’s odd that official PlantUML server uses GraphViz from 2014, I wanted to debug the issue by downgrading GraphViz earlier before I went to PlantUML’s bug-tracker, and for distros like Arch it’s such a pain to find such an ancient version for the dependency. Also, I’ve checked on PlantUML release in-between:

# plantuml -version
PlantUML version 1.2022.4 (Sat Apr 09 13:29:17 GMT 2022)
(GPL source distribution)
Java Runtime: OpenJDK Runtime Environment
JVM: OpenJDK 64-Bit Server VM
Default Encoding: UTF-8
Language: en
Country: US

PLANTUML_LIMIT_SIZE: 4096

Dot version: dot - graphviz version 4.0.0 (0)
Warning : cannot determine dot version

The issue seems to be fixed for the following diagram:

@startuml BrokenSVG

class User {
  email: String
  username: String
  password: String
}

note right of User::username {
  This breaks connections
}

class Role {
  email: String
  name: String
}

User -- Role
Role -- Role
