And this line is responsible for the stackoverflow:

+ ", value={}", entry.getKey(), entry.getValue());

To be more precise it happens when processing the map entry "cocoon". So in
this case there must be some circular reference.. finding that needle is a bit
more difficult :(

Actually you can see it if you start the cocoon-sample block and request
http://localhost:8888/controller/abc/foo?reqparam=1
SLF4J: Failed toString() invocation on an object of type [java.util.HashMap]
java.lang.StackOverflowError

It actually happens in STRenderer
public String render(final String template,
final Map<String, Object> parameters)
throws IOException {
final ST stringTemplate = new ST(template, '$', '$');
if (parameters == null || parameters.isEmpty()) {
LOG.warn("There are not any parameters passed to the template.");
} else {
for (Map.Entry<String, Object> entry : parameters.entrySet()) {
stringTemplate.add(entry.getKey().replace(".", "_"),
(entry.getValue() instanceof String)
? StringEscapeUtils.escapeXml(
entry.getValue().toString())
: entry.getValue());
LOG.debug("Passing pipeline parameter as attribute: key={}"
+ ", value={}", entry.getKey(), entry.getValue());
}
}
return stringTemplate.render();
}
