Product: iRise Studio
 Version: v8.11.0 upwards

This article describes a workaround if Studio fails to launch due to the known Java bug 7180557 : InetAddress.getLocalHost throws UnknownHostException on java7u5 on OSX - http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7180557.

Locate the studio.log file in /Users/username/Library/Logs/iRise/Studio for the existence of the following error:

ERROR com.irise.studio.StudioMain -

It appears that this machine is affected by http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=7180557.

This affects iRise Studio's proper operation. As a workaround to correct the problem, you can edit /etc/hosts and add the machine's host name to the line containing '127.0.0.1 localhost' and/or '::1 localhost'. The host name can be found by opening Terminal and running 'hostname -s'. The value entered in /etc/hosts must match this value exactly. For further assistance, please contact iRise Support.

 Instructions on how to locate the Studio log are in the following KB: http://support.irise.com/customer/portal/articles/567566-irise-studio-enterprise-edition-for-mac---locating-files

a) Unzip and download the following script to your Home folder (/Users/username): addhostname.sh.zip
 
 b) Open a Terminal window and at the prompt, type:
 
 sudo -s
 
 c) At the bash# prompt, type:
 
 sh addhostname.sh
 
 d) Type exit to quit from the bash# shell
 
 e) Check that the loopback address 127.0.0.1 and hostname has been appended correctly to the bottom of the hosts file by typing:
 
 cat /etc/hosts
 
 f) Launch Studio
 
 If you still have trouble launching iRise Studio, please contact support@irise.com with a copy of your studio.log and details of the entries in the /etc/hosts file.
