NPE using XmlLogger and antlib

           Summary: NPE using XmlLogger and antlib
           Product: Ant
           Version: 1.6.2
          Platform: Other
        OS/Version: Other
            Status: NEW
          Severity: Critical
          Priority: Other
         Component: Core tasks
        AssignedTo: dev@ant.apache.org
        ReportedBy: mariano@fuegolabs.com


I put down the problem to a simple procedure to reproduce:
I have sample.xml and antlib.xml, I just define the antlib in sample.xml and
when I try to run it with the XmlLogger I get this:

mariano@fenix:/w/MAIN/local/modules/boot.launcher> ant -f sample.xml -logger
org.apache.tools.ant.XmlLogger
Buildfile: sample.xml
<?xml version="1.0" encoding="UTF-8"?>
<?xml-stylesheet type="text/xsl" href="log.xsl"?>

<build time="0 seconds" error="/w/MAIN/local/modules/boot.launcher/sample.xml:5:
srcdir attribute must be set!">
        <task name="java.lang.NullPointerException
        at
org.apache.tools.ant.util.DOMElementWriter.encode(DOMElementWriter.java:174)
        at
org.apache.tools.ant.util.DOMElementWriter.write(DOMElementWriter.java:95)
        at
org.apache.tools.ant.util.DOMElementWriter.write(DOMElementWriter.java:113)
        at org.apache.tools.ant.XmlLogger.buildFinished(XmlLogger.java:189)

        at org.apache.tools.ant.launch.Launcher.main(Launcher.java:55)


this happens because the antlib taskname is null, I debugged it and found that
the taskname attribute of the antlib is never defined. and when the logger
receives the taskStarted for the antlib, it stores a null for the value, and
that breaks the XmlLogger.

I really need this to be able to use CruiseControl with our ant project, since
it uses it extensively as I understand.
