Henri Biestro resolved JEXL-136.
--------------------------------
Resolution: Fixed
Changed logic of Interpreter.call to narrow only after trying all other
possibilities.
jexl2/src/main/java/org/apache/commons/jexl2/Interpreter.java

Committed revision 1359338.
> Script calls within scripts may fail with number arguments
> ----------------------------------------------------------
>
> Key: JEXL-136
> URL: https://issues.apache.org/jira/browse/JEXL-136
> Project: Commons JEXL
> Issue Type: Bug
> Affects Versions: 2.1.1
> Reporter: Henri Biestro
> Assignee: Henri Biestro
> Fix For: 2.1.2, 3.0
>
>
> Jexl attempts to narrow arguments when solving function names; unfortunately,
> this may cause issues when the function is a script and the argument type is
> expected to remain untouched.
> The map key in the following code is an Integer; by calling the function
> fn01, the interpreter fails to find a method and retries after 'narrowing'
> the argument which becomes a Byte. The Byte is not equal to the Integer map
> key with the same value; the test fails.
> {code}
> @Test
> public void test136() throws Exception {
> JexlEngine jexl = new Engine();
> JexlContext jc = new MapContext();
> JexlScript script;
> JexlExpression expr;
> Object result;
> script = jexl.createScript("var x = $TAB[idx]; return x;", "idx");
> jc.set("fn01", script);
> script = jexl.createScript("$TAB = { 1:11, 2:22, 3:33}; IDX=2;");
> script.execute(jc);
> expr = jexl.createExpression("fn01(IDX)");
> result = expr.evaluate(jc);
> assertEquals("EXPR01 result", 22, result);
> }
> {code}
