Description

Hello,

We are hitting an issue with Saxon PE 9.7.0-21 where java code is invoked from XQuery and gets passed a HashTrieMap where a regular Map was expected.

Here is code to reproduce this:

package org.talend.transform.xquery.test;

import java.util.HashMap;
import java.util.Map;

import org.junit.Test;

import net.sf.saxon.s9api.Processor;
import net.sf.saxon.s9api.Serializer;
import net.sf.saxon.s9api.XQueryCompiler;
import net.sf.saxon.s9api.XQueryEvaluator;
import net.sf.saxon.s9api.XQueryExecutable;

public class Tdm8225Test {
	
	@Test
	public void t() throws Exception {
		
		String script = "xquery version \"1.0\";\n" + 
				"declare namespace tdm8225Test = \"java:org.talend.transform.xquery.test.Tdm8225Test\";\n" + 
				"\n" + 
				"let $xml := <rootElement>\n" + 
				"    <elementA>a</elementA>\n" + 
				"    <elementA>b</elementA>\n" + 
				"    <elementA>b</elementA>\n" + 
				"    <elementA>b</elementA>\n" + 
				"    <elementA>a</elementA>\n" + 
				"    <elementA>c</elementA>\n" + 
				"    <elementA>c</elementA>\n" + 
				"    <elementA>c</elementA>\n" + 
				"    <elementA>c</elementA>\n" + 
				"    <elementA>c</elementA>\n" + 
				"</rootElement>\n" + 
				"\n" + 
				"return for $key in $xml/elementA\n" + 
				"  return tdm8225Test:getValue(tdm8225Test:getMap(), $key)";
		
        Processor proc = new Processor(true);
        ActivateSaxon.activate(proc);
        XQueryCompiler comp = proc.newXQueryCompiler();
        XQueryExecutable exp = comp.compile(script);
        Serializer out = proc.newSerializer();
        out.setOutputProperty(Serializer.Property.METHOD, "xml");
        out.setOutputProperty(Serializer.Property.INDENT, "yes");
        out.setOutputProperty(Serializer.Property.OMIT_XML_DECLARATION, "yes");
        out.setOutputStream(System.out);
        
        XQueryEvaluator eval = exp.load();
        eval.run(out);

	}

	public static Map<String, String> getMap() {
		Map<String, String> myMap = new HashMap<>();
		myMap.put("City","Bonn");
		return myMap;
	}
	
	public static String getValue(Map<String, String> map, String key) {
		return map.get(key);
	}
}
