Have you done any further research? I had a look at the place in the code:
public void setParameter(String name, String namespace, Object value)
{
VariableStack varstack = getXPathContext().getVarStack();
QName qname = new QName(namespace, name);
XObject xobject = XObject.create(value, getXPathContext());
StylesheetRoot sroot = m_stylesheetRoot;
Vector vars = sroot.getVariablesAndParamsComposed();
int i = vars.size();
while (--i >= 0)
{
ElemVariable variable = (ElemVariable)vars.elementAt(i);
if(variable.getXSLToken() == Constants.ELEMNAME_PARAMVARIABLE &&
variable.getName().equals(qname))
{
varstack.setGlobalVariable(i, xobject);
}
}
}
vars.size() is in ine 1497 and causes the NPE. I don't know how you can enforce
this NPE. Bug the CVS on TransformerImpl
(http://cvs.apache.org/viewcvs.cgi/xml-xalan/java/src/org/apache/xalan/transformer/TransformerImpl.java)
shows a fix near to the in the stacktrace mentioned line (refering to bug
#25368). The patch is included in the new Xalan 2.6.0 version, so maybe you try
this one. It's included in recent Cocoon 2.1 from CVS.
Please report back. Otherwise we have to put the blame on your stylesheet (or
your usage in general) or on Xalan and close the bug.
