Use Java version 8 for CI build #30

Using Java 11 for the build process is probably causing the following crash on Android 9. Using Java 8 should be a safer option.

Fatal Exception: java.lang.NoSuchMethodError: No virtual method flip()Ljava/nio/ByteBuffer; in class Ljava/nio/ByteBuffer; or its super classes (declaration of 'java.nio.ByteBuffer' appears in /system/framework/core-oj.jar)
