Description
When the query contains space, it throws exception. E.g. below endpoint should work.
https://hostname/actuator/metrics/jvm.memory.used?tag=area:heap,id:Eden%20Space
query is tag=area:heap,id:Eden Space, in L86, encode() will encode whitespace as %20. And in L87, impl of restTemplate.getForObject, it encodes the url again, making it %2520, causing the 404.
