onlineeeeee opened a new issue, #2116:
URL: https://github.com/apache/logging-log4j2/issues/2116
I have set
System.setProperty(Log4jPropertyKey.CONTEXT_SELECTOR_CLASS_NAME.getSystemKey(),
AsyncLoggerContextSelector.class.getCanonicalName()); before
LogManager.getLogger.
sometimes it work as AsyncLoggerContext, sometimes get LoggerContext.
I found out that this is due to the fact that the methods returned by the
JVM's getMethods do not guarantee order
in the code org.apache.logging.log4j.plugins.di.DefaultInjector method
registerBundleInstance
c.getDeclaredMethods() is disordered, in method createMethodBindings, it
getMethodName from scopes, if method defaultContextSelector before
systemPropertyContextSelector init into scopes, then LogManager.getLogger while
return LoggerContext, but it must be AsyncLoggerContext.
`
// registerBundleInstance method
Stream.<Class<?>>iterate(moduleClass, c -> c != Object.class,
Class::getSuperclass)
.flatMap(c -> Stream.of(c.getDeclaredMethods()))
.filter(method ->
AnnotationUtil.isMetaAnnotationPresent(method, FactoryType.class))
.forEachOrdered(method -> {
if (method.getDeclaringClass().equals(moduleClass) ||
providerMethods.stream().noneMatch(m ->
m.getName().equals(method.getName()) &&
Arrays.equals(m.getParameterTypes(),
method.getParameterTypes()))) {
final var bindings = createMethodBindings(bundle,
method);
if (!bindings.isEmpty()) {
providerMethods.add(method);
bindings.forEach(binding ->
merge(binding.getKey(), binding));
}
}
});
// createMethodBindings method
...
final Supplier<T> factory = getScopeForMethod(method).get(primaryKey,
unscoped);
...
// getScopeForMethod method
final Annotation methodScope = AnnotationUtil.getMetaAnnotation(method,
ScopeType.class);
return methodScope != null ? getScope(methodScope.annotationType()) :
getScopeForType(method.getReturnType());
// getScope method
public Scope getScope(final Class<? extends Annotation> scopeType) {
return scopes.get(scopeType);
}
