rules_kotlin should migrate off @bazel_tools//tools/java:java_stub_template.txt

[hvadehra]

It's used in a couple of places

rules_kotlin/src/main/starlark/core/compile/cli/toolchain.bzl

Line 74 in 096170f

default = Label("@bazel_tools//tools/java:java_stub_template.txt"),

and

rules_kotlin/kotlin/internal/jvm/jvm.bzl

Line 139 in 096170f

default = Label("@bazel_tools//tools/java:java_stub_template.txt"),

The template now lives in @rules_java and in Bazel@HEAD the target in @bazel_tools is just a redirect. Given that the template is no longer versioned with Bazel, it can no longer be considered stable, and the Bazel team is looking to make bazel_tools empty in future releases anyway.

The code expanding the template must remain in sync with the template, the recommendation is to fork the template and maintain a local copy that matches the template expansion code. This will enable rulesets to evolve independently and keep the template always in sync with the rule code.
