tests don't compile when building with OpenJDK
tests don't compile when building with OpenJDK

I get this error when compiling with "make openjdk=...." on both x86_64 and
arm:

compiling test classes
test/Arrays.java:90: error: reference to equals is ambiguous, both method
equals(float[],float[]) in Arrays and method equals(Object[],Object[]) in
Arrays match
      expect(java.util.Arrays.equals(null, null));

test/Arrays.java:95: error: reference to hashCode is ambiguous, both method
hashCode(double[]) in Arrays and method hashCode(Object[]) in Arrays match
      java.util.Arrays.hashCode(null);

The attached patch fixes this.
