Could you please attach log from tmc-cli - it should be available at ~/.config/tmc-cli/logs/tmc-cli.log

The issue has been fixed in the underlying libraries and now in tmc-cli with de4607311624d8c6a38a5dc8baebf13abfca0ac4. We'll release a new release shortly with the bugfix.

Thanks for for submitting the issue varesa! Could you please try version 0.4.2, it should be fixed now.

~/.config/tmc-cli/logs/tmc-cli.log from old version:

2016-06-09 19:34:10 INFO TmcCore:87 - Creating new ListCourses command 2016-06-09 19:34:17 INFO TmcCore:87 - Creating new ListCourses command 2016-06-09 19:34:18 INFO TmcCore:82 - Creating new GetCourseDetails command 2016-06-09 19:34:18 INFO TmcCore:76 - Creating new DownloadOrUpdateExercises command

I tested the new version and it works:

[esa@esaf ~]$ tmc download 2016-aalto-c A new version of tmc-cli is available! Do you want to download it? (y/N): n Exception in thread "main" java.lang.ExceptionInInitializerError ...

[esa@esaf ~]$ alias tmc=/home/esa/tmc.new [esa@esaf ~]$ tmc download 2016-aalto-c [Module_1-02_intro, Module_1-04_func, ...

I also figured out that installing the package java-1.8.0-openjdk-develfixed the issue in the older version
