I'm not sure if it is the same problem but...
We use VA Java as a development IDE, and in the past we had a problem where
a class that we exported from VA Java could not be loaded by any other JVM.
After working with IBM we found that it is because VA Java had a bug and it
was exporting a java class with invalid byte codes. The error we'd recieve
when trying to load this class was very similar to what you are getting.
I'd try writing a small test stub that uses the class loaded to load the
class, and test on a couple of different JVM's. The class file that you
have may be corrupt. If it fails to load in other JVM's as well, you'll
have to contact the authors of the class and see what can be done.
Hope this helps.

Subject: Urgent help needed
Hi all,
I am using Netscape Iplanet Web Server and JSP.I am trying out a
cryptography module. Now my application is made and is working fine
using Tomcat on a trial basis. But when I put these application on
iPlanet, JSP Compiler is throwing an Classformat error. It is showing
the message for a particular Java class which is used for cryptography.
The specific message is Illegal constant pool type.
Given below is the error message::
failure ( 4941): Internal error: exception thrown from the servlet
service function (uri=/cryptix/intro.jsp): java.lang.ClassFormatError:
