Context

During test of:

• https://forum.plantuml.net/19714/multiple-separate-diagrams-in-one-file-is-it-possible

Question or bug report

• How to the plantuml servers (this plantuml-server, the old online plantuml server or the new online server) manage multiple diagrams on the same file or same text area?

The output seems funny... 😃
Here are some tests with the new online editor.

Example

@startuml(id=TAG1)
Alice->Bob : TAG1
@enduml

@startuml(id=TAG2)
Alice->Bob : TAG2
@enduml

@startuml
class Car {
  +String make
  +String model
  +int year
}
@enduml

@startuml
Alice -> Bob: Authentication Request
Bob --> Alice: Authentication Response

Alice -> Bob: Another authentication Request
Alice <-- Bob: Another authentication Response
@enduml

Or:

@startuml
participant Participant as Foo
actor       Actor       as Foo1
boundary    Boundary    as Foo2
control     Control     as Foo3
entity      Entity      as Foo4
database    Database    as Foo5
collections Collections as Foo6
queue       Queue       as Foo7
Foo -> Foo1 : To actor 
Foo -> Foo2 : To boundary
Foo -> Foo3 : To control
Foo -> Foo4 : To entity
Foo -> Foo5 : To database
Foo -> Foo6 : To collections
Foo -> Foo7: To queue
@enduml

@startjson
{
   "fruit":"Apple",
   "size":"Large",
   "color": ["Red", "Green"]
}
@endjson
