Given the following tree:

 /
 ├── a
 ├── b
 └── b0

 NodeUtil.getUniqueName(session, "/", "a")  = "a0"
 NodeUtil.getUniqueName(session, "/", "b")  = "b1"
 NodeUtil.getUniqueName(session, "/", "b0") = "b1"
 NodeUtil.getUniqueName(session, "/", "c")  = "c"
 

Throws:

javax.jcr.RepositoryException

getUniqueName

public String getUniqueName(javax.jcr.Session session,
