jsp:setProperty doesn't work with short properties

Question

Hi,
          Setting bean properties doesn't work with properties that are of type short.
          Any ideas what's going on? I'm using WLS 6.1SP1 on W2K.
          --John
          <jsp:useBean id="test" scope="session" class="test.Test" />
          <jsp:setProperty name="test" property="*" />
          -- Test.java
          package test;
          * @author john
          public class Test {
          /** Creates new Test */
          public Test() {
          public short getShort() {
          return 0;
          public void setShort(short val) {
          Produces the following error while attempting to compile the jsp:
          Compilation of

It looks like a bug in JSP generator. If you look and the .java
          created by 6.1 it doesn't make any sence:
          String _propertyValue = request.getParameter("short");
          if (_propertyValue != null && !_propertyValue.equals(""))
          test.setShort(null);
          (needless to say that this works correctly in Resin).
