Research direction
Locate the Java binary wrapper script and read the existing manifest-jar workaround for long classpaths. Compare it with JDK 9 argument-file support and determine the compatibility approach for older --javabase versions; done means the wrapper uses argument files when targeting JDK 9 and addresses the stated older-version case.
Written by the indexing model from the issue text.
Description
The Java binary wrapper script works around command line length limits by creating a jar file with a Class-Path manifest entry containing the long classpath (related: bazelbuild/bazel#6289).
JDK 9 adds support for flag files using the @argument-file syntax, see "java Command-Line Argument Files" in https://docs.oracle.com/javase/9/tools/java.htm.
We should use that instead of the manifest jar hack when targeting JDK 9.
We could back-fill support for that syntax for older --javabase versions by adding logic to the wrapper script.
