Question

GUI stopped working on Ubuntu 13.04. Used version 7976 with openjdk-7-jre-headless:amd64 (/usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java) Please fix this as soon as possible or provide a work around since it is a blocking issue. The error is:

Answer 1

Hello, Could you give some information on how this happens. Is it when you start the GUI? When you click somewhere ? Were older versions of PlantUML working on this config ? Thanks

Comments

When I start the application. It does not show any of my .txt files. It also reports the error again when I change directory. Never files are being shown because of this error so I cannot use the application.

Answer 2

Ah, this solved it:

    $ sudo apt-get install graphviz

The GUI resulted in an PNG in which an error was about missing dot but this was not directly obvious to me.

A bit of a silly error. Nevertheless, the GUI should report this nicely to the end user. Please implement something for this.

Ok thanks.
Not sure to have understood why this happens, but we will catch the Exception to turn arround the problem.
