The node that holds the lock can be deleted. No Exception is thrown even though the mixin=mix:lockable with a deep lock is present on the node.

CODE:

// Use the JPA connector (it's the same for the inmem connector).
Session session1 = RepositoryReferenceFactory.getRepository("test-jpa").login();
Session session2 = RepositoryReferenceFactory.getRepository("test-jpa").login();
LockManager lm1 = session1.getWorkspace().getLockManager();

// Create dir structure
Node root1 = session1.getRootNode();
Node node1 = root1.addNode("node1", "nt:folder");
Node node2 = root1.addNode("node1/node2", "nt:folder");
Node node3 = root1.addNode("node1/node2/node3", "nt:folder");
session1.save();

// Lock the second node
node2.addMixin("mix:lockable");
session1.save();
lm1.lock("/node1/node2", true, false, 10000, "Locked");
session1.save();

// Attempt to delete the locked node
session2.refresh(true);
Node toDelete = session2.getNode("/node1/node2");
toDelete.remove();
session2.save();
