Min Java SDK at 1.7 or 1.8?

[chalin]

We follow gRPC Java in requiring JDK 7+, as specified in the Quick start, for example:

I've noticed that in some of the examples/stub*/build.gradle.kts files, the sourceCompatibility is set to 1.8; for example:

grpc-kotlin/examples/stub/build.gradle.kts

Line 26 in 6c6078c

sourceCompatibility = JavaVersion.VERSION_1_8

My questions:

• Should this be 1.7?
• Why isn't the same setting used in stub-android/build.gradle.kts?

I used JDK 8 in the samples so that we can use kotlin("stdlib-jdk8") but we probably aren't taking advantage of anything in there so we can see about just using kotlin("stdlib") which I think is JDK 7 compatible.

We aren't really using the Java stuff in the Android sample which is why we don't need to set java settings.

Thanks for the explanation. @jamesward, can you make this change in the example config?
