Generated classes by exec-model will be defined by ProjectClassLoader.

But they are firstly searched with Class.forName() by its parent classloader which is a waste of time.
DynamicProjectClassLoader.java
protected Class<?> loadClass(String name, boolean resolve) throws ClassNotFoundException { try { return loadType(name, resolve); } catch (ClassNotFoundException cnfe) { try { return projectClassLoader.internalLoadClass(name, resolve); } catch (ClassNotFoundException cnfe2) { return projectClassLoader.tryDefineType(name, cnfe); } } }
ProjectClassLoader.java
public Class<?> internalLoadClass(String name, boolean resolve) throws ClassNotFoundException { if (CACHE_NON_EXISTING_CLASSES && nonExistingClasses.contains(name)) { throw dummyCFNE; } if (droolsClassLoader != null) { try { return Class.forName(name, resolve, droolsClassLoader); } catch (ClassNotFoundException e) { } } try { return super.loadClass(name, resolve); } catch (ClassNotFoundException e) { return Class.forName(name, resolve, getParent()); } }
