> Namespace functors are not cleared when the classloader is updated
> ------------------------------------------------------------------
>
> Key: JEXL-432
> URL: https://issues.apache.org/jira/browse/JEXL-432
> Project: Commons JEXL
> Issue Type: Bug
> Affects Versions: 3.4.0
> Reporter: Vincent Bussol
> Assignee: Henri Biestro
> Priority: Major
> Fix For: 3.4.1
>
>
> Using a cache-enabled engine, when the classloader is updated, nodes with
> namespace functor values are not cleared and still use the previous version.
> From the "ClassCreatorTest" class, here is a test to illustrate the issue:
> {code:java}
> @Test
> public void testFunctorFour() throws Exception {
> final ClassCreator cctor = new ClassCreator(jexl, base);
> cctor.setSeed(2);
> cctor.setCtorBody("value = (Integer) ctxt.get(\"value\") + 10;");
> Class<?> foo1 = cctor.createClass(true);
> assertSame(foo1.getClassLoader(), cctor.getClassLoader());
> assertEquals("foo2", foo1.getSimpleName()); final Map<String,
> Object> ns = new HashMap<>();
> ns.put("test", foo1.getName());
> // use cache
> final JexlEngine jexl2 = new
> JexlBuilder().namespaces(ns).cache(16).create();
> jexl2.setClassLoader(cctor.getClassLoader());
> cctor.clear(); final JexlContext ctxt = new MapContext();
> ctxt.set("value", 1000);
> final JexlScript script = jexl2.createScript("test:getValue()");
> Object result = script.execute(ctxt);
> assertEquals(1010, result); cctor.setSeed(2);
> cctor.setCtorBody("value = (Integer) ctxt.get(\"value\") + 99;");
> final Class<?> foo11 = cctor.createClass(true);
> assertEquals("foo2", foo1.getSimpleName());
> assertNotSame(foo11, foo1);
> foo1 = foo11;
> // drum rolll....
> jexl2.setClassLoader(foo1.getClassLoader());
> result = script.execute(ctxt);
> // tada!
> assertEquals(1099, result);
> } {code}
> A solution could be to add the "NamespaceFunctor" to the list of instances to
> clean (JexlNode#clearCache()).
