我正在使用Jackrabbit 2.13.1。
为什么AccessDeniedException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,这将引发AccessDeniedException:
Caused by: javax.jcr.LoginException: Workspace access denied

at org.apache.jackrabbit.commons.AbstractRepository.login(AbstractRepository.java:144)

session为null,因此无法调用注销。但是会抛出未关闭的会话检测到的异常:
WARN o.a.jackrabbit.core.SessionImpl - Unclosed session detected. The session was opened here:

最佳答案
很好,这听起来很像,它仍然存在于2.13.3
中,并且在SessionImpl
的构造函数中抛出异常的情况下会发生,因此将听起来很清晰,然后部分地创建了会话,但仍将其视为 Activity 会话当前代码会将即将被GC视为会话泄漏,这就是为什么您收到此警告。
