.deb Linux package crash: java.lang.IllegalArgumentException: invalid version

[schirmermischa]

I have installed the v3.5.1 .deb package without problems reported by the installer.
Upon launch, I get the following Warnings, and ultimately a "severe" exception:

org.weasis.launcher.WeasisLauncher: Cannot not start framework: java.lang.IllegalArgumentException: invalid version "": invalid format

Thank you very much for looking into this!

I forgot to say that i'm running on kubuntu 18.04.

I just try on a live cd and I don't see any issue.

Did you change something? because you have an empty version value!

[schirmermischa]

I haven't changed anything. I pulled the v3.5.1 deb package from the repository and run the executable "as is".

[schirmermischa]

Before trying the .deb package, I compiled weasis from source, but the viewer-linux.sh script ran into problems not finding its own configuration and .jar files. I have adjusted $curPath accordingly in that script, but then other files were not found, so I went for the binary instead.

[nroduit]

Could you run /opt/Weasis/Weasis in CLI and post the configuration part especially "last running version" and "current version"

[schirmermischa]

Dear Nicolas,

running it the first time I ran into the same problem. The spalsh screen displaying all modules being loaded, then it crashes, with "last running version" being an empty string.

***** Configuration *****
Last running version =
Current version = 3.5.1

I then ran it a second time, piping the output to a logfile, and it did not crash.
***** Configuration *****
Last running version = 3.5.1
Current version = 3.5.1

I closed the terminal, and ran it again, and it launches fine without crashes. It appears to be stable now. Many thanks for providing the .deb package, I much appreciate it!

[nroduit]

There was something wrong with the previous version. I made a fix in the future release to let run even the old version is not valid.

Removing the folder {user}/.weasis should also solve the problem.
