I'd guess this is more related to AWT than cocoon. This the source of
the method the exception is thrown in (taken from JDK 1.4, the line
numbers are different to your stack trace so I guess you are using JDK
1.3 but the code is probably similar). The stack trace originates inside
the anonymous class. Maybe this will help you locate the cause of the
trace.
/**
* Gets the default toolkit.
* <p>
* If there is a system property named <code>"awt.toolkit"</code>,
* that property is treated as the name of a class that is a subclass
* of <code>Toolkit</code>.
* <p>
* If the system property does not exist, then the default toolkit
* used is the class named <code>"sun.awt.motif.MToolkit"</code>,
* which is a motif implementation of the Abstract Window Toolkit.
* <p>
* Also loads additional classes into the VM, using the property
* 'assistive_technologies' specified in the Sun reference
* implementation by a line in the 'accessibility.properties'
* file. The form is "assistive_technologies=..." where
* the "..." is a comma-separated list of assistive technology
* classes to load. Each class is loaded in the order given
* and a single instance of each is created using
* Class.forName(class).newInstance(). This is done just after
* the AWT toolkit is created. All errors are handled via an
* AWTError exception.
* @return the default toolkit.
* @exception AWTError if a toolkit could not be found, or
