plantuml (8028) makes dot/graphviz crash on Win and OSX

[ascheman]

We currently have an AsciiDoctor Maven project which uses PlantUML.
One of the diagrams make dot/GraphViz crash from the attached PUML file (html5-architecture.puml.zip) on OSX and Windows. It works on Linux.

From the plantuml project we got the hint that this is solved in the 8037 version (cf. http://plantuml.com/plantuml/svg/bL0nJiGm4EppYbLeG28Leg6W80YTu910INU-OcKlYR6nZuqDH8Y_4mUEHEYGZiwUdPcTsSvejq769sZHgLVM8P23m94ovnL1VXaDbTx1ehvTdkRmdgskxoDnBvZfEMecmSPvQNmCWgDJn9tqJEjiDIe4brLriiu-lkqMTNqtkk0ZlatmqakqLV2C3NqjgS3Ei8avvh4UpKYxeLwc3mpyqcfo8J47AAef-WLAGqxbS61rquQ6iK_Q6gtf15_XYnzgq_3SkYMF51IAuXmE_-OTmHc4D3qM_B0TpvI_Ikocpwj34JUZS9yJxxRxkSy-uJ66Tgxuv_Oa_mG0).

Could you please update asciidoctor-diagram to use the latest plantuml version?

The diagram is part of the following project:

https://github.com/dukecon/dukecon.git

Just check it out and run "mvn generate-resources" on Win7 or OSX to find the broken SVG in target/generated-docs/de/images/html5-architecture.svg.

Thanks,

PlantUML <plantuml@gmail.com> suggested to use the latest version and give it a try. I updated my local asciidoctorj-diagram-1.3.1.jar with a new gems/asciidoctor-diagram-1.3.1/lib/plantuml.jar. However, the current version of plantuml (8041) has an API incompatibility since a class was dropped. This leads to an execution error:

Failed to execute goal org.asciidoctor:asciidoctor-maven-plugin:1.5.3:process-asciidoc (generate-html-doc-de) on project dukecon: Execution generate-html-doc-de of goal org.asciidoctor:asciidoctor-maven-plugin:1.5.3:process-asciidoc failed: An API incompatibility was encountered while executing org.asciidoctor:asciidoctor-mavenplugin:1.5.3:process-asciidoc: java.lang.NoSuchMethodError: net.sourceforge.plantuml.OptionFlags.setDotExecutable(Ljava/lang/String;)V

It is already solved in the current plantuml beta and should be published in the next official version.

The issue is really on PlantUML side:
Due to some internal refactoring, we have removed the method OptionFlags.setDotExecutable()

We will restore it in next official release that will be published before the end of the month.
You can already test it using last beta https://dl.dropboxusercontent.com/u/13064071/plantuml.jar

Thanks for pointing this out!

I've updated PlantUML to v8041. The Java code now does a lookup of the setDotExecutable via reflection. It will use the OptionFlags variant if available and the GraphvizUtils variant as fallback.

[arnaudroques]

Thanks for the quick work-around! We'll still publish a corrected version, because other tools may also be impacted by this setDotExecutable move.

@ascheman fyi I'm going to publish 1.5.0 with this fix asap. Noticed some CI test failures on Windows that I still want to investigate further first.

Thanks @pepijnve, but there is no hurry required. I have my local workaround with the patched 1.3.1 version for OSX and on my Linux based CI server it was working anyways.
