mvn install hangs in HistoryPersistenceTest

[PerBothner]

I can't mvn build because it hangs here:

This is on Fedora 27 with Java 8:

java version "1.8.0_144"

This is with a fresh

git clone git://github.com/jline/jline3.git

Is that specific to your environment ? I've tried to reproduce it on several platforms without success.
If you can reproduce it easily, could you grab a thread dump with a kill -3 ?

[PerBothner]

log1.txt
log2.txt

log1.txt is copied from te terminal I was running mvn install in. log2.txt is from te terminal I used to kill it.

I can upload the dumpStream file if that would be useful.

This looks like a regression caused by #140 and which causes the CI jobs to fail too.
