Description

Dmesg on CentOS7 displays the following warning:

[   22.742524] warning: `jsvc' uses 32-bit capabilities (legacy support in use)

To reproduce we run the following on CentOS 7:

1) Install Tomcat 8.0.36

wget -O /tmp/tomcat8.tgz http://apache.saix.net/tomcat/tomcat-8/v8.0.36/bin/apache-tomcat-8.0.36.tar.gz
 
cd /tmp
tar -zxvf /tmp/tomcat8.tgz
mkdir /usr/share/tomcat8
mv /tmp/apache-tomcat-8.0.36/* /usr/share/tomcat8

2) Compile native library

yum install apr-devel gcc make zlib-devel
 
tar -xvzf /usr/share/tomcat8/bin/tomcat-native.tar.gz -C /tmp
cd /tmp/tomcat-native-1.2.7-src/native/
./configure --with-apr=/usr/bin/apr-1-config --with-java-home=/usr/java/default/ --with-ssl=no --prefix=/usr/share/tomcat8
make
make install

3) Compile jsvc

## Extract and compile from source:
tar -xvf /usr/share/tomcat8/bin/commons-daemon-native.tar.gz -C /tmp/
cd /tmp/commons-daemon-*-native-src/unix
./configure --with-java=/usr/java/latest
make
 
## Adjust permissions/ownership and move the executable into place
chmod a+x jsvc
mv jsvc /usr/share/tomcat8/bin/
 
 
## Test that the compiled version works
/usr/share/tomcat8/bin/jsvc --help

Tomcat 8.0.36 ships with DAEMON 1.0.15. I am not sure if the above compile settings are wrong or we are missing something?
