Code block macro interpreting its contents in 5.8.16
Asked by Teresa Hollidge:

On a Confluence page we have an XML code snippet that includes a CDATA section, contained within a code block macro. This worked fine in Confluence 5.3.4 and 5.8.10.

```

```

However, in 5.8.16 if I edit the page and attempt to save or close, the browser becomes unresponsive. If I attempt to insert the code snippet into a new page, the page will save but the snippet will be truncated just before the end of the CDATA section. In 5.8.16 it seems that the code block is trying to interpret the CDATA section.

Here's the error in the log file:

```

I upgraded both of my production instances to 5.8.16 last weekend before I discovered this issue. I can rewrite this code snippet to resolve the immediate problem. I'd prefer CDATA to be handled correctly within code blocks or at least fail gracefully because I never know when someone will add another code snippet like this one.

Or did I miss something? Is there a flaw in my assessment?

Thanks!

Teresa
