Subject [jira] [Commented] (SUREFIRE-1255) Surefire 2.19.1 hangs before starting test execution
Date Mon, 29 Aug 2016 08:57:20 GMT

    [ https://issues.apache.org/jira/browse/SUREFIRE-1255?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15445295#comment-15445295
] 

Tibor Digana commented on SUREFIRE-1255:
----------------------------------------

If the main process is killed after specified timeout, STDIN would not
know and the CI would not be able  to perform {{mvn clean}}.

> Seeing the same error as SUREFIRE-1193 in Apache Flink builds after upgrading from 2.18.1
to 2.19.1. No errors, builds just gets stuck at the beginning of tests with no log output
from the test itself, e.g. https://s3.amazonaws.com/archive.travis-ci.org/jobs/137118454/log.txt
> After a couple of minutes Surefire reports

> We have a a couple of test classes that suffer from this problem. Tests don't read from
STDIN or replace it. Switching back to 2.18.1 eliminates the problem (Ran over 100 builds).
It seems to be a race condition because it only occurs every once in a while, i.e. ~ 2 out
of 10 builds on Travis. I haven't been able to reproduce the problem locally.
