Symptoms

When trying to view tasks by going to Profile > Tasks, no tasks appear even though they are assigned correctly.

The following appears in the atlassian-confluence.log:

2014-09-16 20:14:16,706 ERROR [http-bio-8090-exec-64] [[Standalone].[localhost].[/confluence].[noop]] log Servlet.service() for servlet [noop] in context with path [/confluence] threw exception [Servlet execution threw an exception] with root cause
java.lang.NoClassDefFoundError: com/atlassian/labs/speakeasy/ui/CssVariableTransformer$CssVariableDownloadableResource

Diagnosis

Occurs when running Confluence greater than 5.1.5 with the Speakeasy plugin installed

Cause

Speakeasy only supports Confluence up to 5.1.5, and when used in greater versions can break the Tasks list.

Workaround

Disable the Speakeasy plugin.
