When using dropwizard 1.0.7 with jetty-proxy 9.3.9.v20160517 I am seeing a NoClassDefFoundError when instantiating the ProxyServlet.Transparent class.

Upgrading to dropwizard 1.1 with jetty-proxy 9.4.2.v20170220 fixed the problem for me.

The issue can be reproduced from the following repository: https://github.com/rsb5003/proxy-server-test.

Since using Dropwizard 1.1.x seems to work and a workaround is available for Dropwizard 1.0.x, we will not fix this nuisance in Dropwizard 1.0.x.

@joschi I updated my test project with the <scope>compile</scope> as you recommended. That solved the problem with being able to instantiate the ProxyServlet.Transparent class!

Thanks for you help in looking into this problem! I think my team will likely upgrade to dropwizard 1.1.0 anyway, however this is great to know there is a possible solution while still using dropwizard 1.0.x
