Java: generated API including square brackets in request URL

[jack]

Hello,

Using a swagger generated java client for the Transport for London unified API (definition: https://api.tfl.gov.uk/swagger/docs/v1).

The generated client is forming the calls to the API by calling toString on the array parameters, which then includes the square brackets and causes the request to fail.

Using swagger codegen maven plugin version 2.3.1.

Is this down to a mistake in the swagger definition or in swagger itself?

Example: https://api.tfl.gov.uk/Line/Mode/%5Btube%2C%20dlr%5D/Status?detail=true

What it should be: https://api.tfl.gov.uk/Line/Mode/tube%2Cdlr/Status?detail=true

Any help much appreciated!
