Short circuit validation in bind handler if previous exception is present

[mbhave]

For a class that looks like this

@Validated
static class ExampleCamelCase {

	@Valid
	private InnerProperties inner = new InnerProperties();

	InnerProperties getInner() {
		return this.inner;
	}

	static class InnerProperties {

	        @Min(5)
		private int personAge;

		int getPersonAge() {
			return this.personAge;
		}

		void setPersonAge(int personAge) {
			this.personAge = personAge;
		}

	}

}

personAge is validated twice. Since we only throw one validation exception, we can skip validation if a previous validation exception is present.
