Carlos Sanchez closed MNG-2459.

Assignee: Carlos Sanchez
Resolution: Won't Fix
You probably need to make java task to fork the jvm, see ant documentation. In
any case this is not a maven bug.
> Problem parsing XML in code run using antrun plugin
> ---------------------------------------------------
>
> Key: MNG-2459
> URL: http://jira.codehaus.org/browse/MNG-2459
> Project: Maven 2
> Issue Type: Bug
> Components: Ant tasks
> Affects Versions: 2.0.4
> Environment: Red Hat Enterprise Linux WS release 4 (Nahant Update 3)
> java version "1.5.0_06"
> Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_06-b05)
> Java HotSpot(TM) Client VM (build 1.5.0_06-b05, mixed mode, sharing)
> Reporter: Kris Nuttycombe
> Assigned To: Carlos Sanchez
> Attachments: antrun-log4j-xml-test.tgz

>
> I'm not certain whether this is an antrun problem or a log4j problem, but
> considering that the same application run from the command line has no
> problems, I'm going to point to antrun as the first possible culprit.
> This error occurs when I attempt to use the antrun plugin to run a standalone
> Java program that is, for deployment, packaged as a jar-with-dependencies jar
> using the assembly plugin. I use antrun during development for the purpose of
> giving me the benefit of the classpath information from the POM; if there's a
> better way of doing this I'd be happy to work around the problem.
> The error appears to occur when log4j attempts to parse an XML configuration
> file using the DOMConfigurator. It appears that the DocumentBuilderFactory
> package name is being prepended with "com.sun." when the application is run
> using the antrun plugin. Is there some aspect of Maven or of the antrun
> plugin that is altering the XML parsing environment?
