bazel run probably fails on long classpaths

[ekuefler]

This report is based off reading source code rather than something I've actually repro'd, so apologies if I'm missing something.

Linux tends to limit the max length of a command line to around 128k. This can be a problem for Bazel java compilation since it requires jars for every transitive dep to be specified in the classpath. The java run script attempts to mitigate this by echoing the classpath to a file and using it as an @argfile. But argfiles are only implemented in stock JDK in Java 9, which public Bazel isn't using. So I believe this will fail if anyone tries to bazel run a Java binary with a large number of transitive deps.

Guess it's a bug. But will label as P4 because I failed to repro. (Got Java "too many constants" JVM error before this "bug")

Closing as "Won't Fix - obsolete".
It was not reproducible and we have moved beyond the JVMs in question.
