Description

regression of JCR-2425

in certain scenarios, calling SessionItemStateManager.getIdOfRootTransientNodeState() may cause a NPE.

Test case:

Repository repository = new TransientRepository();
Session session = repository.login(
new SimpleCredentials("admin", "admin".toCharArray()));
Session session2 = repository.login(
new SimpleCredentials("admin", "admin".toCharArray()));

try {
while (session.getRootNode().hasNode("test"))

{ session.getRootNode().getNode("test").remove(); }

Node test = session.getRootNode().addNode("test");
session.save();
Node x = test.addNode("x");
session.save();

Node x2 = session2.getRootNode().getNode("test").getNode("x");
x2.remove();
x.addNode("b");
session2.save();
session.save(); // throws NPE
} finally

{ session.logout(); session2.logout(); }
