A DESCRIPTION OF THE PROBLEM :
Our application was running fine on jdk131_03 but when we ported weblogic sp1 to sp4(jdk131_08) we had the following problem..
The line of code in the jsp is :
<H3>Welcome <bean:write name="user" property="username[1]"/>!</h3>
where 1 is a input parameter of getUsername(int size) method of FormBean. In my case "name" is not an array... 1 is an int passed to the method getUsername(int size) from my JSP through <bean:write> tag. Input exactly means that i want 1 char of the String.

It Looks like the change in the introspector class(in jdk131_08) has affected
this.
