manejo de excepciones okhttp

Cuando use OKhttp para crear OkHttpClient para solicitar la red, se lanzará una excepción

java.lang.BootstrapMethodError: Exception from call site #5 bootstrap method
    at okhttp3.internal.Util.<clinit>(Util.java:87)
    at okhttp3.internal.Util.immutableList(Util.java:234)
    at okhttp3.OkHttpClient.<clinit>(OkHttpClient.java:127)
    at com.amazonaws.transcribestreaminghttpclient.MainActivity.<init>(MainActivity.java:28)
    at java.lang.Class.newInstance(Native Method)
    at android.app.AppComponentFactory.instantiateActivity(AppComponentFactory.java:69)
    at android.support.v4.app.CoreComponentFactory.instantiateActivity(CoreComponentFactory.java:43)
    at android.app.Instrumentation.newActivity(Instrumentation.java:1215)
    at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2831)
    at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:3048)

Para el manejo de este problema, JakeWharton dio la respuesta, que es agregar el archivo build.gradle

android { 
    compileOptions { 
        targetCompatibility = "8" 
        sourceCompatibility = "8" 
    } 
}

Vuelve a ejecutarlo está bien
