Why am I getting overlapping arrows and text in a state uml diagram?

Question

I am new to plantuml so I may be doing something stupid. I have a state transition diagram with overlapping arrows and text. See E->B and B -> E - the text T and Z are overlapping.

@startuml

 

A --> B : P

C --> E : R

E --> C : S

E --> B : T

B --> E : Z

 

state A {

  state C {

    state E {

    }

  }

}

 

state B {

}

This is not a solution but will raise the T to prevent overlap:
E --> B : T\n

or just change the order of your transitions ...
I tried B -> E moving to the top already works...

Hello,

It's a bug... but not sure that this will be easy to fix : There are too many imbricated states.

Anyway, thanks for the report!

I put a breakpoint in the code and pulled the generated dot file contents into a text file and ran dot manually. It has the same problem. I think this might be a problem with dot, not plantuml. I could not figure out any settings that would force dot to generate the correct diagram.
