How can I add JSON highlighting to the code in Jira comment?

Is it possible to add a highlighted code to Jira comment? I want to write something like this:

The comment text and JSON doc:

{
  "key": 100
}

I've found only one example:

{code:javascript}
{
  "key": 100
}
{code}

But it does not really highlight my code. I see only the grey block.

Solution 1:

You can try to add only {code} at the beginning and end of your code block.

Example:

{code}
{
  "key": 100
}
{code}

Solution 2:

Recent Jira 7.5+ starts supporting more languages, including JSON.

Simply use:

{code:json}
...
{code}
