Item14617: PlantUML ditaa diagrams do not work any more

Instead of rendering ditaa diagrams, the plantuml plugin now produces error messages. This happened on Foswiki-2.1.4, Plugin API version 2.4, perl 5, version 24, subversion 1, PlantUML (8050beta0), dot - graphviz version 2.38.0, OpenJDK 64-Bit Server VM 1.8.0_151-8u151-b12-1~deb9u1-b12, Debian Stretch.

PlantUMLPlugin Error: failed to execute "java -jar /opt/plantuml/plantuml.jar -tpng /tmp/PjaddL6ZXB/GVJZlExtWI.plantuml", RC=256
output: Error line 3 in file: /tmp/PjaddL6ZXB/GVJZlExtWI.plantuml
Some diagram description contains errors

Text:
ditaa(--no-shadows, scale=0.8)

Unable to reproduce with

• Foswiki 2.1.4
• Plugin API 2.4
• Perl 5.16.3
• OpenJDK 1.8.0_161-b14
• graphviz 2.38.0
• PlantUML 1.2018.01

Used the following plantuml example as a test, results were identical to the image on the plantuml web site:

<plantuml>
ditaa(--no-shadows, scale=0.8)
/--------\   +-------+
|cAAA    +---+Version|
|  Data  |   |   V3  |
|  Base  |   |cRED{d}|
|     {s}|   +-------+
\---+----/
</plantuml>

Note that I'm using mod_perl and not fcgi (fast cgi). I'd suggest getting the latest plantuml jar file and restarting your web server. The error you're seeing is a plantuml error so it seems likely to be an issue with that version of plantuml.

I'm using mod_perl as well.

As a workaround, I have copied and modified the PlantUMLPlugin into a DitaaPlugin and additionally installed the ditaa package on my machine. This works. To handle Options like no-shadows or scale, I have created a parameter named 'options'.
