JDK 1.6 - Confluence Standalone Tomcat - OS: Linux

Here is an example of my problem if I try to view the first issue of the "D8" project:

{jira:D8-1|server=Company Issue Tracking}

The macro above yields the following result:

"The JIRA server was not able to process the search. This may indicate a problem with the syntax of this macro..."

However, if I create a project with a key "DD", the following example works great:

{jira:DD-1|server=Company Issue Tracking}

Apparently, it's the numeric values within the project key that stop the Jira Connector from seeing anyting with that project.
