As reported by customer, when using the following configuration:

if (BuildConfig.DEBUG) {
            StrictMode.setVmPolicy(new StrictMode.VmPolicy.Builder()
                    .detectLeakedSqlLiteObjects()
                    .detectLeakedClosableObjects()
                    .penaltyLog()
                    .penaltyDeath()
                    .build());
        }

the following errors are logged:

A resource was acquired at attached stack trace but never released. See java.io.Closeable for information on avoiding resource leaks.

This library is now end-of-life and this issue won't be fixed. This issue has been tagged EOL in case any forks want to import it.
