I am using ignite within a spring application using JCache API. Application
is throwing NPE when starting up.
-- exception ----
Caused by: java.lang.NullPointerException: null
at
io.micrometer.core.instrument.binder.cache.JCacheMetrics.<init>(JCacheMetrics.java:80)
Spring is loading ignite correctly as you can see from below log:
-------------------
[15:08:08] Ignite node started OK (id=66e75cae)
[15:08:08] Topology snapshot [ver=9, servers=2, clients=1, CPUs=4,
offheap=6.4GB, heap=2.8GB]
[15:08:08] ^-- Node [id=66E75CAE-FB54-401F-9330-CEBDA3A7EB84,
clusterState=ACTIVE]
-------------
Adding an entry into the cache as part of a service bean's postconstruct
method is working. So the CacheManager is correctly autowired. I am able to
successfully add an entry into a cache.
-------------- Service bean ---
@Autowired
private CacheManager cacheManager;
@PostConstruct
public void setup() {
Cache cache = cacheManager.getCache("users");
cache.put("user","daya");
logger.info("****** added user to cache ***********");
}
---- application.properties -------------

--- JCacheMetrics code where NPE is getting thrown --------------
public JCacheMetrics(Cache<?, ?> cache, Iterable<Tag> tags) {
super(cache, cache.getName(), tags);
try {
String cacheManagerUri =
cache.getCacheManager().getURI().toString()
.replace(':', '.'); // ehcache's uri is prefixed with
'urn:'
this.objectName = new
ObjectName("javax.cache:type=CacheStatistics"
+ ",CacheManager=" + cacheManagerUri
+ ",Cache=" + cache.getName());
} catch (MalformedObjectNameException ignored) {
throw new InvalidConfigurationException("Cache name '" +
cache.getName() + "' results in an invalid JMX name");
}
}

cache.getCacheManager() is returning null.
Please help as we are not able to use ignite. JCache integration is failing
for us because of this.
This is strange as I was able to use the autowired cacheManager to retrieve
a Cache and add an entry.
