I run a single user instance of Atlassian Confluence and yesterday I upgraded to version 5.5. My Confluence wiki worked fine after the upgrade. However, after a reboot when I tried to access my wiki using its usual URL I received this error:

This page can’t be displayed

• Make sure the web address http://localhost:8090 is correct. 

• Look for the page with your search engine. 

• Refresh the page in a few minutes.

I checked to see if the Atlassian Confluence service had started, and it has not, so I tried to do that manually. I received this more helpful error message:

Windows could not start the Atlassian Confluence service on Local Computer.

Error 2: The system cannot find the file specified.

My sys admin skills are few but I uncovered https://confluence.atlassian.com/display/DOC/Setting+the+JAVA_HOME+Variable+in+Windows which led me to try changing the JAVA_HOME system environment variable from C:\Program Files (x86)\Java\jdk1.6.0_35 to C:\Progra~2\Java\jdk1.6.0_35 but this did not help (even after a reboot).

I am reasonably sure that a Java upgrade I accepted recently may be involved in this error. I am using Windows 7 SP1 and have these subfolders present in C:\Program Files (x86)\Java:

  • jdk1.6.0_35
  • jre7

Can anyone advise on whether they know a solution for how to restore my Atlassian Confluence 5.5 to a working condition?


It's a bug introduced in v5.5 - see CONF-33492.

The linked issue includes a simple registry hack workaround.
