Maven occasionally hangs within Surefire
I'm trying to fix a build issue where Maven hangs running tests. This
happens about 30% of the time on our Travis builds.
It never happens on our Jenkins cluster, but it happens occasionally on
some of our local machines. We were able to capture a jstack and lsof from
the process after it hung.
Any tips on how to debug? Relevant captured data is here:
https://gist.github.com/tpetr/1bdd2cfd362f125b4f06
I can't file an issue here [1] as I don't have an account.
Thanks;

It took me some digging, but you use a 30 second fork-timeout (configured
in the uppermost basepom-foundation). And you increased some sleep times in
that module earlier today... :-)
Might that be it?

Thanks for the tip, Andreas.
This seems to have moved us from one problem to another; now we see this
error (again only on Travis and some machines and not on our Jenkins - and
far more often on Java 7 than 8 -
https://travis-ci.org/HubSpot/Singularity/builds/38833718):
[ERROR] Failed to execute goal
org.apache.maven.plugins:maven-surefire-plugin:2.18-SNAPSHOT:test
(default-test) on project SingularityService: There was a timeout or other
error in the fork -> [Help 1]

Hi there,
I bet that's a bug that we already fixed for Surefire 2.18 - you could try
a current snapshot version to verify if it works for you.
Jira issue:
https://jira.codehaus.org/plugins/servlet/mobile#issue/SUREFIRE-1091
We are planning to release 2.18 soonish, definitely this year ;-).

It would be equally interesting to see the jstack of the *other* java
process at the same time, since these two processes communicate with
each other. It looks like the booted process is waiting for something
from the main java launcher...
