Description

I have noticed that when i call lambda.curry() method inside the script, then the curried lamba is created with wrong source text. I expect the source text of the curried lambda to be always equal to that of original, but that is not the case now. To illustrate this I have prepared two testcases, from which testCurryScript2 fails with

[ERROR] Failures:
[ERROR]   LambdaTest.testCurryScript2:307 expected:<true> but was:<false>

    @Test
    public void testCurryScript() throws Exception {
        JexlEngine jexl = new Engine();
        JexlScript base = jexl.createScript("(x, y, z)->{ x + y + z }");
        String text = base.toString();
        JexlScript script = base.curry(5, 15);
        Assert.assertEquals(text, script.toString());

        JexlEvalContext ctxt = new JexlEvalContext();
        ctxt.set("s", base);
        script = jexl.createScript("return s");
        Object result = script.execute(ctxt);
        Assert.assertEquals(text, result.toString());

        script = jexl.createScript("return s.curry(1)");
        result = script.execute(ctxt);
        Assert.assertEquals(text, result.toString());
    }

    @Test
    public void testCurryScript2() throws Exception {
        JexlEngine jexl = new Engine();
        JexlScript base = jexl.createScript("var base = 0; var sum = (y, z) -> {var x = base; x += y; return x}; base = 2; var y = sum.curry(1); y.toString() eq sum.toString()");
        Object result = base.execute(null);
        Assert.assertEquals(Boolean.TRUE, result);
    }
