4
5 Problem
6 : If you have a `<taskdef>` in your `build.xml`, ant will evaluate the specified `classpath` when processing the `<taskdef>`. However, if you are using a `loaderRef`, ant will only evaluate the `classpath` at the first time a `<taskdef>` with the specified `loaderRef` is instantiated and reuse this classloader later. This can cause problems when the classpath reference changes later (e.g. because JAR files are placed in a directory that is used in the `FileSet` used to define the classpath reference).

9 : Define tasks as late as possible and only use a common classloader if you have to share objects between tasks.
