Does Confluence not support syntax highlighting for Java properties files?

[Bogdan Calmac]

I don't see it in the list of formats for the Code macro and it seems strange to have been overlooked when the  Atlassian suite is built on Java.

The macro supports custom languages. I haven't seen JAVA Properties on the web anywhere.

Confluence uses the SyntaxHighlighter library. It's pretty simple. It's javascript and regex.

I see Java, Java FX, and Javascript in the list of formats.
