From a cursory inspection of org.apache.tools.ant.AntClassLoader, it

No, Ant almost always delegates to the system classloader first.
AntClassLoader has a parentFirst option that can be used to make it look
into its own classes before delegating when set to false (it is true by
default). The list of packages you've found are the packages that will
always be loaded from the system classloader even if parentFirst is
false.
I've run into an issue with ant's classloading strategy. When I try to
run a Java class with the<java> task, I get a ClassNotFoundException
for com.sun.xml.internal.ws.spi.ProviderImpl.
Are you sure the class is available from the system classloader?
It's in java 1.6.0_20,
package com.sun.xml.internal.ws.spi;
public static class ProviderImpl extends javax.xml.ws.spi.Provider { ... }
looks like part of JAX-WS
