Subject [jira] [Commented] (BUILDR-607) Java Process Forking
Date Sat, 20 Aug 2011 16:03:27 GMT

    [ https://issues.apache.org/jira/browse/BUILDR-607?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13088205#comment-13088205
] 

Ian Nowland commented on BUILDR-607:
------------------------------------

When I run this on my OS X system instead of my CentOS system, the system out still doesn't
print to the console, but killing the console process does kill the server. A ps, however,
still shows two running processes.

> While running a simple test with a buildr-scala-JERSEY-JETTY setup, the java process
is forking, such that printlns are not going to the console the process was started in, and
killing that process does not kill the jetty server. It's certainly not a blocker, but it
is annoying.
