Iterating over the "disabledServices" set and inserting the found oid(s) into it leads to ConcurrentModificationException when the set contains multiple entries. The proposed fix is to iterating over the array converted from the set which is also used for debugging output instead of the "disabledServices" set itself.

Don't think you need this import.
