failure at times with child modules.
As a note, with beta 3, if I ran this:
$ mvn clean cm-package:package
everything worked (sorry cm-package is a local plugin :| )
However with beta 7, I get a NPE
{{{ Caused by: java.lang.NullPointerException at org.codehaus.mojo.webstart.util.DefaultArtifactUtil.artifactContainsClass(DefaultArtifactUtil.java:211) at org.codehaus.mojo.webstart.JnlpDownloadServletMojo.resolveJarResources(JnlpDownloadServletMojo.java:490) at org.codehaus.mojo.webstart.JnlpDownloadServletMojo.execute(JnlpDownloadServletMojo.java:180) at org.apache.maven.plugin.DefaultBuildPluginManager.executeMojo(DefaultBuildPluginManager.java:134) }}}

This only fails when performed from a "parent" module, if run in the child it works OK. Just thought I'd report it.
Could you give us a example's project which prove the defect. thanks.
