Leak in TranscoderUtil

Question

public static void main(String[] args) throws IOException {
    Transcoder defaultTranscoder = TranscoderUtil.getDefaultTranscoder();
    String encoded = defaultTranscoder.encode(
            "Alice -> Bob: Authentication Request\n" +
            "Bob --> Alice: Authentication Response\n" +
            "@enduml");
}

 

When start tag is missing, it just eats all my free RAM (13GB).

It would probably never happen to IntelliJ plugin users, but perhaps it is related to 502 Bad Gateway which PlantUML Server returns for such input.

Hi,

Many thanks for the feedback : this is indeed a terrible bug!

We just fix it in last beta https://dl.dropboxusercontent.com/u/13064071/plantuml.jar

We have also upgraded the online server with this beta.

Do not hesitate to post again if you find other issue!

Thanks again
