Somewhere between the June 1 and current build, the "target" attribute of the "ant" task seems to have stopped working:
 
<ant dir="sub" target="main2"/>
 
Class class org.apache.tools.ant.taskdefs.Ant doesn't support the "target" property
        at org.apache.tools.ant.ProjectHelper.configure(ProjectHelper.java:451)
 
The Ant class does indeed have a java.lang.String property named "target", and it has a proper setTarget(String s) method.  However, its superclass Task also has a setTarget() method, but the property data type is Target, not java.lang.String.  This is enough to confuse the BeanInfo into ignoring the setTarget() method in Ant.
 
It definitely works in the June 1 version, but I can't tell why - the configure() method in ProjectHelper was not changed.
 
Any ideas?
