    Description

      An exception is thrown when adding indexed properties to a DynaBean. This worked perfectly with Version 1.8.3

      Test Class:
      import org.apache.commons.beanutils.BeanUtilsBean;
      import org.apache.commons.beanutils.LazyDynaBean;

      public class BeanUtilsBeanTestApp {

      public static void main(String[] args) {
      try

      { LazyDynaBean lazyDynaBean = new LazyDynaBean(); BeanUtilsBean beanUtilsBean = BeanUtilsBean.getInstance(); beanUtilsBean.setProperty(lazyDynaBean, "x[0]", "x1"); beanUtilsBean.setProperty(lazyDynaBean, "x[1]", "x2"); System.out.println(lazyDynaBean.get("x")); // output using commons-beanutils 1.8.3: [x1, x2] }

      catch (Exception e)

      { e.printStackTrace(); }

      }
      }
