commons-lang3 was pulled in transitively via the optional gremlin-core dependency but used directly in production code (DefaultLoadBalancingPolicy). Since gremlin-core is optional, consumers would not get commons-lang3 transitively, risking NoClassDefFoundError at runtime. Replace Pair<Integer, Integer> with int[] in moveReplicasToFront() and ArrayUtils.addAll() with standard Arrays.copyOf()/System.arraycopy() in VectorCodecTest.
Fix pre-existing xml-format-maven-plugin check failure.
