I have a couple of different issues with the new RC1 build. On my mac project, I get the following error when starting devmode from the initellij debug launch config

I suspect it is something dumb on my part. It was working OK with a significantly earlier snapshot build.

I'd say you have apache-jsp libs in your WEB-INF/lib: https://github.com/gwtproject/gwt/issues/9343

On a much larger project on Windows, again using Intellj I get the following error

That could be an incompatibility between libs. Given that this happens in ArgHandlerServer and with its default value (ToolBase#processArgs at line 291), I'd say maybe you have dependencies on other Jetty libs with versions different from the one used by GWT. AFAICT, Jetty really requires all its libs to be from the exact same version, as things could break even between minor (or even "patch") versions if you mix them.

The Mac project is pretty much nearly all client code. The only lib it includes in web inf is junit. To be clear this is using the sdk version of Gwt, not maven.

Can you share the full classpath in both cases? and the full content of the WEB-INF/lib directory in the first case?

(btw, JUnit in WEB-INF/lib‽)

I am away from a computer for a week. When I get back I will provide more details. I can remove junit. Not sure why it was there.

Here is the class path. I removed JUnit (it wasn't in web-inf/lib, just on the path).

I reset my project from scratch and it is now working. There must have been some residual stuff left from the last snapshot build I used. I will try the same with the other project.

FWIW, regarding the ServiceConfigurationError: https://github.com/gwtproject/gwt/issues/9343

I managed to get everything working. It was a combination of having gwt-user and gwt-dev on the classpath and some older Tomcat servlet classes.
