Container build sometimes hangs and keeps the thread waiting forever

[raigoinabox]

In my project I investigated an issue where a long-running batch task never finished, but seemed to pause right in the middle of it. For hours it never continued until the server was restarted which caused it to exit. It seems digidoc4j is the culprit.

I was able to get the stack trace of the thread that hung: stack trace.txt.

This error happened in digidoc4j version 4.1.1

We have added this to backlog for investigation.
