Post 2.8.0-beta1 : NoSuchMethodError - CharMatcher.javaUpperCase()

[PatrickMadden]

My code compiles just fine in 2.8.0-beta1. However, when I cloned and built from the master branch I get the following error.

Sounds like you have two versions of gwt-dev.jar in your classpath during compilation (the beta1 version and the master branch version).

[tbroyer]

Or possibly (and actually more likely), you have an older gwt-servlet earlier than gwt-dev in the classpath.

[PatrickMadden]

Thank you both. It turns out I did indeed still have another maven module that was referencing GWT 2.8.0-beta1. When I cleaned it up, the issue went away.
