Description

While developing an ANT build.xml script to test some aspects of grails, we need a <groovy> task that invokes an ANT macro which uses a forked <java> task.

This consistently causes a stack overflow in ANT, apparently in the thread that ANT uses to monitor the output of the forked task.

Script that suffers the problem is attached - its the functional-test target's use of <groovy> to call the "grails" macrodef that is the problem when the macrodef uses fork="true" on the <java> task. If fork=false there is no stack overflow.
