I got this problem while trying to make an assembly, with filtered files, from a root project. I created an issue on JIRA with an example: http://jira.codehaus.org/browse/MASSEMBLY-226
If the "filters" parameter would not be readonly, then this bug would be obsolete. Should I modify this? I ask the question because it seems that for some reason, this param became readonly whereas it didn't use to be at first. Cheers! Fabrice
