/**
 * A {@link Tasklet} that wraps a method in a POJO. By default the return
 * value is {@link ExitStatus#COMPLETED} unless the delegate POJO itself returns
 * an {@link ExitStatus}. The POJO method is usually going to have no arguments,
 * but a static argument or array of arguments can be used by setting the
 * arguments property.
