Since I started to use SimpleCache with ExoPlayer I keep getting LeakedCloseableViolation, as soon as I start playing a new file even though I’m calling the cache release method.

Here’s how I’m initializing the player

...
this.simpleCache = new SimpleCache(new File(context.getCacheDir(), "streamCaching"), new LeastRecentlyUsedCacheEvictor(25 * 1024 * 1024), new StandaloneDatabaseProvider(context));
factory = new CacheDataSource.Factory().setCache(this.simpleCache).setUpstreamDataSourceFactory(httpDataSourceFactory);    
...

Then here’s my release code that is called as soon as the player is stopped

  this.player.release();
    if (this.simpleCache != null) {
            this.simpleCache.release();
            this.simpleCache = null;
        }

Any idea why I keep getting these
