public Method get(Object object) {
        return get(object, null);
    }
This will cache methods solved by reflection as reflection is expensive.
Note that if the bundle from which the method is removed/changed you might have
a problem... A ClassCastException might be one indication. Then clearing the cache and retrying it
once to see if it goes away might be a solution.
