Initial Docker based Jenkins startup based on JCasC and job-dsl and pipeline jobs auto-scheduled (via job-dsl 'queue' command) right after their creation that all use a shared Jenkins pipeline library in SVN.

• This did not hurt and led to successful pipeline job executions

  • Re-triggering the failing builds worked

I guess the used org.mapdb v1.0.9 is to blame: there are 3.x releases and quite a few (resolved and unresolved) concurrency issues...

Alternatively, I think, one might also be able to avoid the concurrency problem by locking the cache file creation by oneself in the usage of org.mapdb.DBMaker, that is in jenkins.scm.impl.subversion.SVNRepositoryView.<init>?
