Can I customize syntax highlighting in Eclipse to show octal literals differently?

I think octal literals are Very Dangerous Things™, and I'd like them to be glaringly obvious whenever I read source codes.

There must be a way to do this i开发者_Python百科n Eclipse, right?

So it looks like standard Eclipse cannot be configured to do this? A custom colorer is required?

No, currently you can only configure a color for all Numbers in Preferences > Java > Editor > Syntax Coloring. May I suggest creating an enhancement request at the Eclipse Bugzilla at http://bugs.eclipse.org/ (correct project is imho JDT / text)?
