> Dmesg on CentOS7 displays the following warning:
> {code}
> [   22.742524] warning: `jsvc' uses 32-bit capabilities (legacy support in use)
> {code}
> To reproduce we run the following on CentOS 7:
> 1) Install Tomcat 8.0.36
> {code}
> 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
> {code}
> 2) Compile native library
> {code}
> 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
> {code}
> 3) Compile jsvc
> {code}
> ## 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
> {code}
> 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?
