Start in HttpProxyCacheServer.java at closeSocketInput, releaseSocket, and processSocket, using the stack trace lines as entry points. Reproduce or inspect the Samsung S7/Android SDK 27 failure and determine the expected cleanup behavior when shutdownInput reports ENOTCONN. Done means socket cleanup no longer produces this erroneous error for the reported case, with relevant tests or verification added if the project provides them.
