I have been working very hard behind the scenes to get those issues fixed
The phonegap team was very supportive and helpful and together we were able to get everything worked out.
With this release GWT and Phonegap will play very nicely together.
A new version is now available on google code or from maven central:
<dependency> <groupId>com.googlecode.gwtphonegap</groupId> <artifactId>gwtphonegap</artifactId> <version>184.108.40.206</version> </dependency>
