compressedMimeTypes property does not work as expected about dropwizard HOT 1 OPEN

Hi @jprakashbabu. Dropwizard 2.1.11 and the provided Jetty version 9.4.53 are out of support, so please migrate to a more recent Dropwizard version. In general, we won't provide full support for versions announced to be EOL. The correct place would be the discussion board. Please don't raise a discussion and an issue, usually only one option fits 😉

That being said, I don't see an issue here. When using your include list

server:
  gzip:
    enabled: true
    compressedMimeTypes:
      - text/html
      - text/xml
      - application/x-javascript
      - text/javascript
      - text/css

my JS file gets compressed correctly.

Can you please let me know if I am missing something here (or) is the exclude list taking precedence over the include ?

When checking, if the MIME-type should be compressed, Jetty first evaluates the include list and then additionally validates, that the type is not in the exclude list. The default exclude list however doesn't list application/x-javascript as an excluded MIME-type.
