swagger-ui: Example/Examples in @ApiParam not showing in swagger-ui

At first what we are using:

• Latest Swagger-ui (3.9.3), tested from dist directory and from unpkg.com
• swagger-core 1.5.18 with Java8 and Jersey 2.26

The Problem is our examples are not shown in swagger-ui documentation. If we load our documentation to editor.swagger.io, then it works fine.

Here is an example:

		@ApiParam(value = "Printer config in json format", required = false, example = ApiDocuExamples.PRINTER_CONFIG)
		@FormParam("config") String configJson,

There is no difference in using example or examples we tried both. This is how it looks like in swagger-ui:

Is this a known issue or are we doing something wrong?
