java.lang.VerifyError : Illegal target of jump or branch

[Arnaud Ferrand]

Hi,

We have a problem runing my application on Weblogic 6.1 sp 4 on solaris 8.
The application works correctly on Windows NT. But we got this exception on
SUN (see the end of the message).

This occurs in a jsp including another big with the old include statement
<%@ include file="/Templates/onglets/Methodes.jsp" %>
the Methodes.jsp file defines some variables used in the current jsp so we
can't use the <jsp:include...> tag ! But why does it work on NT ?

Can anybody help us ???

Hi Arnaud,

In the past I've seen this exception because the JSP in question
compiled to have a try catch block that was too large. I forget what
the number of allowable lines is, but you can exceed it when making a
large JSP. What version of the JDK are you using? With WL7 and
JDK1.3.1.03 we see a better error message, but it amounts to the same
thing. We got around this problem by using dynamic includes for large
components. It is a pain to do this in places where you are doing it
only because of this problem, but it has worked for us.

There is also a 'no try blocks' option on weblogic's JSP Compiler, but
I've never played with that much.

As for why you might see it on Solaris, but not NT, I can verify that
we have seen the same behavior before. Maybe the windows VM
implementation allows for try blocks that are larger than the spec.

Either way good luck.
Steven
