-------------------------------------
Summary: Blueprint Spring SpringApplicationContext ClassLoader
implementation not working for loadClass(name, resolve) operation
Key: ARIES-2051
URL: https://issues.apache.org/jira/browse/ARIES-2051
Project: Aries
Issue Type: Bug
Components: Blueprint
Affects Versions: blueprint-spring-1.0.0
Reporter: Piotr Klimczak
Blueprint Spring SpringApplicationContext uses its own ClassLoader.
This class loader implementation however is not handling calls to
loadClass(String name, boolean resolve), which is used by other class loaders.
Therefore if we obtain class loader for app context and use it for example with
Groovy, it will fail as
{code:java}
@Override
public Class<?> loadClass(String name) throws ClassNotFoundException...{code}
Will not be called at all.
Proper implementation should be:
{code:java}
@Override
public Class<?> loadClass(String name) throws ClassNotFoundException {
return loadClass(name, false);
}
@Override
public Class<?> loadClass(String name, boolean resolve) throws
ClassNotFoundException {
for (ClassLoader cl : parentClassLoaders) {
try {
Class<?> c = cl.loadClass(name);
if (resolve) {
resolveClass(c);
}
return c;
} catch (ClassNotFoundException e) {
// Ignore
}
}
throw new ClassNotFoundException(name);
} {code}
