Problem goes away if you just use a java.util.Stack
instead of subclassing.
Looks like a jvm bug to me ... need to find a workaround.
I assigned this to Egon, but I'll keep looking at it.

I reimplemented CMLStack. It no longer extends java.util.Stack

Votes 0
Synopsis Lots of Vector methods are final
Category java:classes_util
Reported Against 1.0.2, 1.1, 1.1.4
Release Fixed 1.2beta1
State Closed, fixed
Related Bugs 4041340, 4089588
Submit Date Aug 15, 1996
Description
A large number of methods in Vector are final. This means
that I can't
create
a new kind of Vector which tracks add/removes for some reason.
A large number of methods in Vector are final. This means
that I can't
create
a new kind of Vector which tracks add/removes for some reason.
Workaround
None.
Evaluation
This is a RFE since the implementation agrees with the spec.
But why are all
these methods final? Is there (or was there) an efficiency
issue?
?????????????????
Methods were final for historical reasons. This has been
fixed in 1.2.

There is definately something wrong with the java.util.Stack
class.
ns jvm 1.1.5 is throwing an error too ... and the information is
a little more helpful:
Symantec Java! ByteCode Compiler Version 210.065
Copyright (C) 1996-97 Symantec Corporation
ReaderFactory: CMLReader
# Verifier error org/openscience/cdk/io/cml/CMLStack:
Class org/openscience/cdk/io/cml/CMLStack overrides final
method toString.()Ljava/lang/String;
java.lang.NoClassDefFoundError:
org/openscience/cdk/io/cml/CMLStack
So, this means we must come up with a workaround.
