JRE logs to stdout and breaks javac/scalac worker on certain environments
ERROR: <redacted>/BUILD:3:14: scala @//<redacted> failed: Worker process returned an unparseable WorkResponse!
Did you try to print something to stdout? Workers aren't allowed to do this, as it breaks the protocol between Bazel and the worker process.

It turned out that recent version of jre logs to stdout (JDK-8272121, JDK-8153723), and may break java bazel woker should any warning logged. It would be nice if we include jvm flags in the toolchain config, so that the jre logs to stderr instead.
Didn't mean to set the labels... they were from the template. Overlooked that.
We're already doing that by default: https://github.com/bazelbuild/rules_java/blob/master/toolchains/default_java_toolchain.bzl#L47-L50
@ashi009 Are you using a different toolchain configuration?
