I'm getting a NullPointerException under the following circumstances:

- 'Maven Dependencies' are added to the 'Web Deployment Assembly'
- I add a dependency to the POM that is another maven project in the same workspace

I also get the error when the situation is reversed:

- The other maven project in the same workspace is already added to the project's POM
- I add 'Maven Dependencies' to the 'Web Deployment Assembly'

Error message is:
An internal error occurred during: "Updating status for Tomcat v6.0 Server at localhost...".
java.lang.NullPointerException


From the .metadata/.log file:

m2e does not directly provide integration with wtp. Please use https://issues.sonatype.org/browse/MECLIPSEWTP to report m2e/wtp integration problems (assuming you are using m2eclipse-wtp).
