trouble with coercision in test

[peutch]

Hi,

Here is a unit test class that reflect my problem:

import static org.junit.Assert.assertEquals;

import java.util.Collections;

import org.junit.Test;

import com.hubspot.jinjava.Jinjava;

public class TestJinjava {
	@Test
	public void testCoerc() {
		String output = new Jinjava().render("{% macro bug(version) %}"
				+ "{% set fversion = 'rawhide' if version == 'rawhide' else 'f' + version|string %}"
				+ "- name: fedora_{{version}}\n"
				+ "  url: 'https://src.fedoraproject.org/rpms/{srcname}/tree/{{fversion}}'\n"
				+ "{% endmacro %}{{ bug('39') }}{{ bug('rawhide') }}", Collections.emptyMap());
		assertEquals("- name: fedora_39\n  url: 'https://src.fedoraproject.org/rpms/{srcname}/tree/f39'\n"
				+ "- name: fedora_rawhide\n  url: 'https://src.fedoraproject.org/rpms/{srcname}/tree/rawhide'\n",
				output);
	}
}

If bug('19') is replaced by bug(19), test is broken:

com.hubspot.jinjava.interpret.FatalTemplateErrorsException: Cannot coerce 'rawhide' of class java.lang.String to class java.lang.Long (incompatible value)

To me this is strange and it is also not possible to replace the condition by something like:
{% set fversion = 'rawhide' if version|string == 'rawhide' else 'f' + version|string %}
isn't it?

This test case was extracted from:
https://github.com/repology/repology-updater/blob/master/repos.d/rpm/fedora.yaml
that use Python Jinja2.
