EOFException when executing remoteant task from ant-contrib

Question

I am trying to be able to launch an ant task remotely using ant-contrib. For testing purposes I have defined a server and a caller with following files.

<?xml version="1.0" encoding="ISO-8859-1"?> 
<project name="RMI" basedir="." default="start.ant.server"> 
      <target name="start.ant.server"> 
                <taskdef resource="net/sf/antcontrib/antcontrib.properties"/> 
                <antserver port="12345" /> 
        </target> 
        <target name="remoteant"> 
                <echo message="hi"/>
        </target> 
</project>

And

<?xml version="1.0" encoding="ISO-8859-1"?> 
<project name="RMI" basedir="." default="call.ant.server"> 
        <target name="call.ant.server">
                <taskdef resource="net/sf/antcontrib/antcontrib.properties"/> 
                <remoteant machine="localhost" port="12345"> 
            <runtarget target="remoteant"/>
        </remoteant>    
        </target> 
</project>

When I start the server and then run the remote call, everything seems to be working fine but the caller throws an exception:

Has anyone found something similar, any way to get rid of the exception?

Thanks,

Seems to be a problem with versions. Ant 1.8.1 with ant-contrib 1.0.3b. http://sourceforge.net/tracker/?func=detail&aid=3323778&group_id=36177&atid=416920 to whoever that want to track the status of this bug. — pedromarce, Mar 02 '12 at 15:57

It is ant-contrib known issue, but you can ignore it with

<trycatch>
       <try>
             <remoteant machine="localhost" port="12345"> 
             <runtarget target="remoteant"/>
        </try>
        <catch>
            <echo>Ignoring known issue: EOF I.O. exception...</echo>
        </catch>
</trycatch>

But that would also catch an issue with the remote host, something that you might want to deal with it, for instance the remote server not being active. Wouldn't it? – pedromarce Aug 08 '13 at 16:15
