Encountering java.lang.IllegalArgumentException

Question

I just updated PlantUML to the latest version and I am now encountering an exception.

The UML was fine with the previous version I was using [1.2018.11]

Here is the console output:

You should send a mail to plantuml@gmail.com or post to http://plantuml.com/qa with this log (V1.2020.00)

Answer 1

Sorry about that...
Could you post your diagram or a minimal example that is not working ?

Thanks,

This is a stripped down version of my UML that exhibits the exception.

@startuml

package MyFoo {
    class MyFoo.MyFoo
}
MyFoo -- Target

package My.Module {
    package My.Module.Defines {
    }
    class My.Module.Class {
    }
    My.Module.Class --> My.Module.Defines
}
My.Module --> MyFoo

Answer 2

Many thanks for the report.

Preparing http://alphadoc.plantuml.com/doc/asciidoc/en/poll-about-package-and-namespace we've done some preliminary refactorings which were supposed to be safe (and which were not :-) )

Anyway, this is fixed in last beta http://beta.plantuml.net/plantuml.jar

Tell us if you find other regressions.

Thanks again and sorry about that !
