Description

I have the following program (it uses the apache-commons-lang3 library)

class Main {
  static final void test() {
    final byte[] vetting = new byte[1];
    final byte[] grafting = org.apache.commons.lang3.ArrayUtils.removeAll(vetting); // works 
    final byte[] grafting = org.apache.commons.lang3.ArrayUtils.removeAll(vetting, 0); // fails 
  }
}

Actual behavior

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
groovy38.groovy: 4: [Static type checking] - Reference to method is ambiguous. Cannot choose between [byte[] org.apache.commons.lang3.ArrayUtils#removeAll(byte[], int[]), long[] org.apache.commons.lang3.ArrayUtils#removeAll(long[], int[]), float[] org.apache.commons.lang3.ArrayUtils#removeAll(float[], int[]), double[] org.apache.commons.lang3.ArrayUtils#removeAll(double[], int[]), int[] org.apache.commons.lang3.ArrayUtils#removeAll(int[], int[]), short[] org.apache.commons.lang3.ArrayUtils#removeAll(short[], int[])]
 @ line 4, column 29.
       final byte[] grafting = org.apache.commons.lang3.ArrayUtils.removeAll(vetting, 0);
                               ^
