-----------------------------------
Summary: 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
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()).
