在 AccessDeniedException 上检测到 Jackrabbit 未关闭的会话，但会话为空

Question

我正在使用 Jackrabbit 2.13.1。

为什么 AccessDeniedException 会导致会话泄漏？

        try {
            session = repository.login(creds); //here are creds for user without permissions, just for testing
        } catch (Throwable t) {
            if (session != null) {
                session.logout();
            }
            Throwables.propagateIfInstanceOf(t, javax.jcr.RepositoryException.class);
            throw Throwables.propagate(t);
        }

如预期的那样抛出 AccessDeniedException：

Caused by: javax.jcr.LoginException: Workspace access denied
    at org.apache.jackrabbit.core.RepositoryImpl.login(RepositoryImpl.java:1529)
    at org.apache.jackrabbit.commons.AbstractRepository.login(AbstractRepository.java:144)
    at ttt.createSession(RepositoryManager.java:132)
    ... 51 common frames omitted

    at org.apache.jackrabbit.core.RepositoryImpl.createSession(RepositoryImpl.java:956)
    at org.apache.jackrabbit.core.RepositoryImpl.login(RepositoryImpl.java:1501)

session 为空，因此我无法对其调用注销。但是未关闭的会话检测到异常被抛出：

WARN  o.a.jackrabbit.core.SessionImpl - Unclosed session detected. The session was opened here: 
java.lang.Exception: Stack Trace

很好，这听起来 显然是 中仍然存在的错误 2.13.3 并且在 [=11= 的构造函数中抛出异常时发生]，然后部分创建了会话，但它仍然被认为是活动的，并且即将被 GCed 的实时会话被当前代码视为会话泄漏，这就是您收到此警告的原因。
