Build with Java 8 due to ByteBuffer NoSuchMethodError (#116, #158)

bp-alex · bp-alex · commit 2f8527b6e651 · 2020-06-03T11:50:47.000+10:00
As detailed at #116, Java 9 introduced overridden methods with covariant return types in ByteBuffer. The consequence is that Java 8 compatibility is problematic if compiling with Java 9 or above. This commit therefore performs the deployment step using Java 8. The fuller verification step is still completed on Java 11.
