Hi, I created a patch for that. Could someone take a look ? I added a special utility class (Java9Bridge) for java 9 migration.

> We use this method in multiple places:
> 1) {{MessageCodeGenerator}}
> 2) {{BinaryContext}}
> 3) {{ClassesGenerator}}
> 4) {{GridUriDeploymentFileProcessor}}
> The problem is that in Java 9 application class loader is not {{URLClassLoader}}, so we cannot get URLs easily. Instead typically it is {{BuiltinClassLoader}}, which refers to {{URLClassLoader}} in it's internal field {{ucp}}.
> Let's refactor all usages of {{URLClassLoader.getURLs}} to some utility method, which will be able to handle both Java 7/8 and Java 9 (through reflection).
