Problem

When setting the umask to 0077 the JIRA Installer does not set files with correct permissions.

Steps to Reproduce

Perform the following steps to reproduce this (as root):

umask 0077
umask
wget http://www.atlassian.com/software/jira/downloads/binary/atlassian-jira-5.1.8-x64.bin
sh atlassian-jira-5.1.8-x64.bin
cd jira_install/
find . -name "ApplicationPropertiesJira*"
cd ./atlassian-jira/WEB-INF/classes/com/atlassian/jira/startup/
ls -la
history | cut -c 8-

Simple example in the folder /atlassian-jira/WEB-INF/classes/com/atlassian/jira/startup

-rw-------  1 root root  1954 2012-10-29 01:27 ApplicationPropertiesJiraHomePathLocator$1.class
-rw-r--r--  1 root root  1658 2012-10-29 01:27 ApplicationPropertiesJiraHomePathLocator.class

Note that in the subclass file the group and global permissions are not set. This is problematic.

Additionally, the shell scripts will not be provided with the appropriate permissions so JIRA will not be able to be started:

[root@hercules tmp]# /etc/init.d/jira start
To run JIRA in the foreground, start the server with start-jira.sh -fg
executing using dedicated user: jira
bash: ./startup.sh: Permission denied

The same goes for upgrades as it does for installs.

Workarounds:

1. Set umask to something else (eg: 0022) prior to installation
2. Fix the file permissions after install:

   chmod -R u=rwx,g=rx,o=rx /var/atlassian/application-data/jira 
   chmod -R u=rwx,g=rx,o=rx /opt/atlassian/jira/
