IllegalMonitorStateException thrown when releasing the lock

This simple test case:

public class SkipLockingTest extends SingleCacheManagerTest {

private AdvancedCache advancedCache;

@Override
protected EmbeddedCacheManager createCacheManager() throws Exception

{ Configuration c = new Configuration(); c.setCacheMode(Configuration.CacheMode.LOCAL); EmbeddedCacheManager cacheManager = new DefaultCacheManager(c); advancedCache = cacheManager.getCache().getAdvancedCache(); return cacheManager; }

public void testExistsInContextPut(Method m)

{ String name = m.getName(); advancedCache.put("k-" + name, "v-" + name); advancedCache.withFlags(Flag.SKIP_LOCKING).put("k-" + name, "v2-" + name); }

}

throws:
