DMN sort function doesn't work on IBM JDK

When running DMN test combination sort( list : [3, 1, 4, 5, 2] ) from FEELFunctionsTest class on IBM JDK, the test fails, because the correct sort method cannot be invoked.

On IBM JDK, the combination tries to invoke method [1] from SortFunction class, which is incorrect, because the second method with just one parameter should be invoked. This behaviour is influenced by IBM JDK returning methods from call [2] in different order.

Notes from debugging:
This check [3] pass because the array there is 3 items long although the last item is not populated. This array is created from this method call [4].
