DynamicProxyable works only with non-primitive arguments

see https://www.couchbase.com/forums/t/reactive-dynamicproxyable-is-not-working/39163

Issue is in FindMethod

spring-data-couchbase/src/main/java/org/springframework/data/couchbase/repository/support/FindMethod.java

Lines 124 to 128 in 10f71c9

	for (k = 0; k < l; k++) {
	if (!testParams[k].isAssignableFrom(currentParams[k])) {
	break;
	}
	}

Could do something like this for int/Integer, but I'm hoping to find something that is less of a hack.

            if(params[j] == int.class && parameterTypes[j] == Integer.class )
                continue;

// primitive types are : int, byte, short, long, float, double, boolean, and char.
// but only int, long, double and boolean are supported.
Flux findAll(int iint, long llong, double ddouble, boolean bboolean);

Others, such as byte, short, float and char don't have an equivalent.

Couchbase JVM Core JsonValue only supports these:
/**
* Helper method to check if the given item is a supported JSON item.
*
* @param item the value to check.
* @return true if supported, false otherwise.
*/
public static boolean checkType(Object item) {
return item == null
|| item instanceof String
|| item instanceof Integer
|| item instanceof Long
|| item instanceof Double
|| item instanceof Boolean
|| item instanceof BigInteger
|| item instanceof BigDecimal
|| item instanceof JsonObject
|| item instanceof JsonArray;
}

Arrays won't work here either. They need to be List or Iterable. see https://github.com/couchbase/couchbase-jvm-clients/blob/41834f54f30be0a4dd7fc9953de0fbaac76255db/java-client/src/main/java/com/couchbase/client/java/json/JsonValue.java#L79-L98
