NPE in Project.resoveFile

[Norris Boyd <nb...@atg.com>]

The following erroneous buildfile:

<?xml version="1.0" encoding="utf-8"?>
<project name="Foo" default="package" basedir=".">
  <target name="copy-properties" depends="prepare">
    <copydir src="../../../../../../../../foo"
           dest="."
           includes="*.java" />
  </target>
</project>

causes a NPE in Ant (v 1.1):

I tried to come up with a patch, but I wasn't sure what the best way was
to report the error and stop the build.

I just submitted a patch which will throw a BuildException instead:

test8.xml:6: The file or path you specified (..\..\..\..\..\..\..\..\foo) is
invalid releative to C:\VAMOS50\SourceExt

Note however that this fix will not be made for Ant 1.1 but will be
available in the nightly builds (Ant 1.2 alpha) if someone commits it.
