toolchain_vanilla: Unset source and target language level versions Closes #9415. The main feature of toolchain_vanilla definition is to support newer Java language versions that the embedded JDK, e.g.: at the time of this CL, toolchain_java could be used to support building with JDK 13 and produce byte code major version 57, using the combination of absolute javabase and toolchain_vanilla: $ bazel build --define=ABSOLUTE_JAVABASE=/use/local/bin/jdk-13 \ --javabase=@bazel_tools//tools/jdk:absolute_javabase \ --host_javabase=@bazel_tools//tools/jdk:absolute_javabase \ --host_java_toolchain=@bazel_tools//tools/jdk:toolchain_vanilla \ --java_toolchain=@bazel_tools//tools/jdk:toolchain_vanilla \ :gerrit Unfortunately, 6ef6d879ab69225d54ecab3db847fb4eff33bbeb sets source and target language levels to Java 8 to restore backwards compatibility, to fix a regression, that was introduced during bump of remote JDK version to Java 11, in bad5a2beb9f8441d97b88d5c4323055e710f72e8. This change restores the neutrality of toolchain_vanilla declaration by unsetting source and target language level versions. So that the bazel invocation in the example above produces byte code major version 57 (Java 13), and not 52 (Java 8) as it is the case before this change.
