Subject [jira] (SUREFIRE-946) Maven hangs on SIGTERM when using Surefire forking (CommandLineUtils.ProcessHook)
Date Wed, 09 Jan 2013 20:18:13 GMT

    [ https://jira.codehaus.org/browse/SUREFIRE-946?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=317056#comment-317056
] 

Kristian Rosenvold commented on SUREFIRE-946:
---------------------------------------------

Process termination is a tremendous PITA. Do not expect this to work at all.

I think it might be safer to send a "TERMINATE" down the commlink and do System.exit() in
the fork.

After pressing Ctrl-C to stop the Maven test run, the process hangs and must be killed with
SIGKILL. From the thread dump, {{CommandLineUtils.ProcessHook}} and {{StreamFeeder}} look
responsible.
