           Summary: ClassCastException due to bad TagHandlerPool name
                    generation of two different tags
           Product: Tomcat 5
           Version: 5.5.26
          Platform: PC
        OS/Version: Windows XP
            Status: NEW
          Severity: normal

Small Eclipse 3.3 WST project

The two different tags below will have the same TagHandlerPool name in the
generated JSP. This will lead to a ClassCastException when accessing the JSP at
runtime.

<bug:hello_world/>

<bug:hello world="true"/>

-------------------
Top of stacktrace :

java.lang.ClassCastException: fr.illod.tomcat.bug.taglib.HelloWorldTag
       
org.apache.jsp.index_jsp._jspx_meth_bug_005fhello_005f0(index_jsp.java:115)
        org.apache.jsp.index_jsp._jspService(index_jsp.java:75)
        org.apache.jasper.runtime.HttpJspBase.service(HttpJspBase.java:98)
        ...

--------------

The error seems to come from the "createTagHandlerPoolName" method in
org.apache.jasper.compiler.Generator.java
