Missed dependency? java.lang.IllegalStateException: It appears there is no ServiceLocatorGenerator installed

I’ve upgraded from Dropwizard 0.8 to 1.0.2. Running my unit tests, I’m seeing this error. Is there a dependency I should be including that Dropwizard doesn’t get transitively?

java.lang.RuntimeException: java.lang.ClassNotFoundException: Provider org.glassfish.jersey.internal.RuntimeDelegateImpl could not be instantiated: java.lang.IllegalStateException: It appears there is no ServiceLocatorGenerator installed.

[andrewaylett]

Calling into JerseyGuiceUtils before running tests can also help. We added a static block to each affected test file, which is painful but effective:

static {
    JerseyGuiceUtils.install((s, serviceLocator) -> null);
}

[GrumpyDBA]

Try this: JerseyGuiceUtils.reset(); Literally just had what looks like the exact same issue in the test I was looking at.

I can’t comment as to the reasons why it fixed it, or indeed if it is a better or worse solution than @andrewaylett’s ( I’d probably use his in future though)
