Hi Felix,

Good to see one more script converted to java.

I wonder if the fact that the test use to run two separate
JVMs was significant. Hopefully it's not.

The changes in TestHttpServer seem OK - this class is shared
by many other tests - so any modifications here is to be taken
with care. I trust you ran all the jdk_net tests?

In B4933582.java:

maybe MyAuthenticator.count should be made volatile (or AtomicInteger).
I don't think it's strictly necessary as I believe our implementation
will only call it in the client thread (which is always the main thread
here) - but it may be a better idea to use AtomicInteger anyway: just
make no assumption :-)

I'd also suggest to use try-with-resource to close in
CacheImpl (int port) and CacheImpl::writeMap to make sure
the file is always properly closed.

best regards,
