Bugs: what's the simplest, easiest way to reproduce this bug? Please provide a minimal example if possible.

bazel run --host_javabase=:jdk8 --javabase=:jdk8 :hello_world

results in
LAUNCHER ERROR: Rlocation failed on C:/openjdk/bin/java.exe, path doesn't exist in MANIFEST file

Relevant files (BUILD and HelloWorld.java)

package(default_visibility = ["//visibility:public"])
java_library(
name = "hello_lib",
srcs = glob(["*.java"]),
)

java_binary(
name = "hello_world",
main_class = "hello.HelloWorld",
runtime_deps = [
":hello_lib",
],

package hello;
public final class HelloWorld {
public static void main(String[] args) throws Exception {
System.out.println("Hello, world!");
}
}

What operating system are you running Bazel on?

Windows Server Core 1803

What's the output of bazel info release?

release 0.13.0

Have you found anything relevant by searching the web?

After speaking with @jasharpe,

I think there is a bug with the launcher

bazel/src/tools/launcher/launcher.cc

Line 145 in 40f5a77

if (blaze_util::IsAbsolute(path)) {

If the path is absolute, we should return it regardless of whether the manifest file is empty or not
