---------------------------------------
I am trying to run a daemon on port 80 using jsvc and I am getting this error.
I see there has been some discussion about it here:
http://markmail.org/message/hal2o6gyhd4yjs5h?q=jsvc+java.net.BindException:+Permission+denied+list:org.apache.commons.user/#query:jsvc%20java.net.BindException%3A%20Permission%20denied%20list%3Aorg.apache.commons.user%2F+page:1+mid:tq7dndeolrdtzwk4+state:results
but it doesn't look like it's resolved to me. I try start jsvc as the root user
and also passing in "-user root" and when my app starts up I see:

I am using jsvc 1.0.1 on Linux (kernel 2.6.18-6-amd64) with Java HotSpot(TM)
64-Bit Server VM (build 1.6.0-b105, mixed mode).
> [daemon] java fails to bind on port 80
> --------------------------------------
>
> Key: DAEMON-12
> URL: https://issues.apache.org/jira/browse/DAEMON-12
> Project: Commons Daemon
> Issue Type: Bug
> Environment: Operating System: Linux
> Platform: PC
> Reporter: Ostap Bender
> Priority: Blocker
>
> Platform is Ubuntu Linux, kernel 2.6.15 amd64 smp on a dual core processor.
> When I start Tomcat with jsvc and the Http connector on port 80 java fails to
> bind on port 80. I added an extra debug statement in set_caps to tell me when
> set_caps is called. In catalina.out I see before java even tries to bind,
> three
> calls: the first with the value 1216, second with 1024 (CAP_NET_BIND_SERVICE)
> and the last with 0 (downgrade).
> After commenting out set_caps(0) from the jsvc-unix.c Tomcat starts ok.
> What is the reason for the downgrade happening so soon? Is it a race condition
> turned bad by the use of a multiprocessor?
> BTW, the Readme should mention that the module capabilities should be loaded.
