Review comment:
you can drop the else (as keyword and directly do "return Stream.of(new ValidationResult.ValidationError(pointer, "Expected integer but got " + value));") since previous block uses "return"

Review comment:
type.getValueType() == STRING ;)

Review comment:
hmm, wonder if it shouldn't be merged with multipleof impl: org.apache.johnzon.jsonschema.spi.builtin.MultipleOfValidation
we can image make org.apache.johnzon.jsonschema.spi.builtin.MultipleOfValidation.Impl visible in the package and create method return a new MultipleOfValidation.Impl(...., 1) instead of pseudo-duplicating it, would likely be more explicit we reuse this logic as impl.
what do you think?

Review comment:
we need to test with BigInteger and BigDecimal too I guess
