I tend to agree with @tillrohrmann that there is not need for locking there, as there is no sharing of the data-structure between different threads. The same holds for the lock at line 726. So these 2 `synchronized()` clauses could go away. I will have a more thorough look on the whole locking scheme in the class in the following days. But for now I think that this PR could be closed and the JIRA could be updated.
