-----------------------------------------------------
I can reproduce the bug using this simple code:
{code:java}
List<String> docs = new ArrayList<>();
for (int i = 0 ; i < 10000 ; i++) {
docs.add("/any/valid/path");
}
List<Thread> threads = new ArrayList<>();
for (int i = 0 ; i < 32 ; i++) {
threads.add(new Thread(() -> docs.parallelStream().forEach(p ->
session.getObjectByPath(p))));
}
threads.stream().forEach(Thread::run);
threads.stream().forEach(t -> {
try {
t.join();
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
});
{code}
It happens after a short time of execution
The bug seems to be that an extra writeUnlock() is called from CacheImpl
