Log a warning if running under a Java 7 VM.
More precisely, log a warning if lambda expressions or type annotations in our classes would produce an exception. If someone wants to use Retrolambda or a similar tool to rewrite our classes, that's fine with us if it works. And our support for Android is unchanged: The Android toolchain rewrites lambdas and removes type annotations.
This is a step toward removing Java 7 support entirely: #5269
RELNOTES=Introduced a warning log message when running under Java 7. This warning is not guaranteed to be logged when running under Java 7, so please don't rely on it as your only warning about future problems. If the warning itself causes you trouble, you can eliminate it by silencing the logger for
com.google.common.base.MoreObjects$ToStringHelper
(which is used only for this warning). This warning prepares for removing support for Java 7 in 2021. Please report any problems.0357006
