Pie chart throws error when there are more colours than data series

I'm running Confluence 3.5.13. I have a pie chart which graphs a dynamic set of data, which contains up to 4 data series. The color parameter specifies four colour values. When the dataset includes fewer than 4 data series the macro throws a "java.lang.ClassCastException" error.

Eg.

{chart:type=pie|dataOrientation=vertical|colors=maroon,blue,yellow,cyan}
|| Priority || Num Defects ||
| 2 | 1 |
| 3 | 1 |
{chart}

Is this a known issue? Is it going to be fixed?

The problem also exists on Confluence 4.3.2, the error shows as "java.lang.String cannot be cast to java.lang.Integer"

You should report that at jira.atlassian.com, on Confluence project. It seems a bug.

Looks like that's the only way I'll get any help with this - opened https://jira.atlassian.com/browse/CONF-27584.
