Subject: [PATCH] Fix Bazel #10214: JDK 13 introduced a source compatibility
issue.
Upstream: yes (https://github.com/bazelbuild/bazel/commit/0216ee54417fa1f2fef14f6eb14cbc1e8f595821)
Quote from the Java release notes:
The addition of newFileSystem(Path, Map<String, ?>) creates a source (but not binary) compatibility issue for code that has been using the existing 2-arg newFileSystem(Path, ClassLoader) and specifying the class loader as null. [...] To avoid the ambiguous reference, this code needs to be modified to cast the second parameter to java.lang.ClassLoader.
