EhCache 2.10 incompatible types

My project uses a cache registry with a typical StatisticsGateway stats = cache.getStatistics(); method.  However compiling within IntelliJ results in an incompatible types error.  It compiles fine from the command line and from Eclipse.  The nearest I can figure, IntelliJ is thinking cache is an Ehcache interface rather than a Cache object? How do I get IntelliJ to recognize the proper method return?

import net.sf.ehcache.Cache;
import net.sf.ehcache.CacheManager;
import net.sf.ehcache.Ehcache;
import net.sf.ehcache.Element;
import net.sf.ehcache.statistics.StatisticsGateway;

public class CacheRegistry implements InitializingBean, DisposableBean {
   
   private CacheManager cacheManager;

...
for(String cacheName : this.cacheManager.getCacheNames()) {
Cache cache = this.cacheManager.getCache(cacheName);
...
