           Summary: Ant Symlink task generates Null Pointer exception with
                    stack trace when trying to delete symlink
           Product: Ant
           Version: 1.8.0
          Platform: Sun
        OS/Version: Solaris
            Status: NEW
          Severity: normal
          Priority: P2
         Component: Optional Tasks
        AssignedTo: notifications@ant.apache.org
        ReportedBy: brad.macphee@newpace.ca


As you can see below, I'm using the symlink task to delete a symlink.  The
build.xml has been simplified to the very minimum, so my use case isn't really
obvious here, but what I provided still reproduces the problem.  Find the stack
trace at the end of this description.

Here are the details on the environment (java version, build xml, and relevant
directory layout:

masheen# java -version
java version "1.6.0_18"
Java(TM) SE Runtime Environment (build 1.6.0_18-b07)
Java HotSpot(TM) Server VM (build 16.0-b13, mixed mode)


masheen# pwd
/home/bmacphee/project1

masheen# cat build.xml
<?xml version="1.0" encoding="UTF-8"?>
<project name="project1" default="build" basedir=".">
    <target name="build">
        <symlink action="delete" link="Templates"/>
    </target>
</project>
