[jira] (MASSEMBLY-626) NullPointerException in PlexusIoURLResource.getContents

     [ https://jira.codehaus.org/browse/MASSEMBLY-626?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Dennis Lundberg updated MASSEMBLY-626:
--------------------------------------

    Description: 
I have a situation where I can reliably reproduce an NPE during assembly in one dev environment but not in another.  Probably the most notable difference between the environments is that the working one is running Windows and the non-working one is running Linux, but it's not clear why that should matter.  The project is unfortunately part of a large multi-module project so I can't readily attach it here and I haven't yet attempted to boil it down.  So hopefully this stack trace will help:

The relevant bit of the effective POM is pretty simple, but here it is anyway:
