I was getting the following error when I deployed a component into a JBoss container. <geshi> java.lang.NoSuchMethodError: java.lang.String.isEmpty()Z </geshi>

Initially, I thought it was an issue with the classloader. Turns out, I was using a new Java 1.6 feature.

   /**
    * Returns true if, and only if, {@link #length()} is 0.
    *
    * @return true if {@link #length()} is 0, otherwise
    * false
    *
    * @since 1.6
    */
   public boolean isEmpty() {

return count == 0;

</geshi>
