The /usr/share/tomcat7 directory does not have world execute permissions:

# ls -l /usr/share/ | grep tomcat7
drwxr-x---.   3 root  tomcat  4096 Jun  1 18:12 tomcat7

In Openshift 2.2, tomcat7 gears are not able to build and start because the user that the tomcat7 process in the gear is running as is not root or in tomcat7 group.

This results in the `/usr/share/tomcat7/bin/bootstrap.jar` not being readable and then `Error: Could not find or load main class org.apache.catalina.startup.Bootstrap`

In previous versions of tomcat7 (like in EWS 2), the /usr/share/tomcat7 directory was executable by everyone and Openshift 2 gears did not have issues:

# rpm -qa tomcat7
tomcat7-7.0.54-21_patch_05.ep6.el6.noarch
# ls -la /usr/share/ | grep tomcat7
drwxrwxr-x.   3 root  tomcat  4096 Jun  2 08:46 tomcat7

Finally, the /usr/share/tomcat7 is the only directory with the permission issue:

# namei -l /usr/share/tomcat7/bin/bootstrap.jar 
f: /usr/share/tomcat7/bin/bootstrap.jar
dr-xr-xr-x root root   /
drwxr-xr-x root root   usr
drwxr-xr-x root root   share
drwxr-x--- root tomcat tomcat7
drwxr-xr-x root root   bin
lrwxrwxrwx root root   bootstrap.jar -> bootstrap-7.0.70.jar
-rw-r--r-- root root     bootstrap-7.0.70.jar
