I am trying to use the WAR Overlay functionality in the latest IAM. If Packaging is set to 'war' in the pom.xml file, I get the following exception:
eclipse.buildId=M20090917-0800

Command-line arguments: -os macosx -ws cocoa -arch x86 -product org.eclipse.epp.package.jee.product -keyring /Users/tomtalbott/.eclipse_keyring -showlocation

I've tried to pursue this further, by starting with a standard Maven webapp generated from maven-archetype-webapp. If I start adding just about anything to the pom, I can start getting nullpointers of the form:
Caused by: java.lang.NullPointerException

Sometimes it goes away for a bit if I turn off Maven Dependency Management and back on again. But, that doesn't always work.
Below is a reference to another project that had this exception:
http://issues.ops4j.org/browse/PAXCONSTRUCT-77
All of this is on a clean updated Eclipse 3.5.2 with only IAM & Subversive as added plugins. Running on updated Mac OS X 10.5.8.
I need to come up with a solution for my team soon. At this point, I will probably not be looking into IAM any further unless someone gets back soon. I will be evaluating Netbeans next since it supposedly has good Maven integration.
