             Summary: Ignite JMX problem with Spring Boot
                 Key: IGNITE-1900
                 URL: https://issues.apache.org/jira/browse/IGNITE-1900
             Project: Ignite
          Issue Type: Bug
          Components: 1.4
    Affects Versions: ignite-1.4
            Reporter: wmz7year

I use Ignite with Spring Boot.
When start application,Spring Boot will register JMX info.

In IgniteMXBean interface,There is two method getUserAttributesFormatted and getLifecycleBeansFormatted
return Collection<String>
But In JMX DefaultMXBeanMappingFactory.makeParameterizedTypeMapping method will get method
return type.

 final Type rawType = objType.getRawType();
        if (rawType instanceof Class<?>) {
            Class<?> c = (Class<?>) rawType;
            if (c == List.class || c == Set.class || c == SortedSet.class) {
                Type[] actuals = objType.getActualTypeArguments();
                assert(actuals.length == 1);
                if (c == SortedSet.class)
                    mustBeComparable(c, actuals[0]);
                return makeArrayOrCollectionMapping(objType, actuals[0], factory);
            } else {
                boolean sortedMap = (c == SortedMap.class);
                if (c == Map.class || sortedMap) {
                    Type[] actuals = objType.getActualTypeArguments();
                    assert(actuals.length == 2);
                    if (sortedMap)
                        mustBeComparable(c, actuals[0]);
                    return makeTabularMapping(objType, sortedMap,
                            actuals[0], actuals[1], factory);

The Collection<String> will not match any type for this although IgniteKernal return
type is Set.

I think IgniteMXBean interface should change Collection to Set and List
