Start at HttpProxyCacheServer.java, especially waitForRequest at line 218 and WaitRequestsRunnable at line 324, then trace how ThreadPoolExecutor creates workers in the reported stack trace. Reproduce the OutOfMemoryError with AndroidVideoCache 2.7.0 and establish a fix that prevents the reported thread-creation failure without breaking request handling.
