The error "can't find jdk.test.lib.net.SimpleSSLContext in test directory or libraries" sounds a bit like an infrastructure thing which maybe isn't too hard to repair? Maybe we want to give him a day or two and then just push a fix? What do you think (also @Ilarion...)?

FWIW: I suspect SimpleSSLContext may have been relocated in
the mainline, it might have a different package name / may
need a different @library tag to build it in 11u.

`find test -name SimpleSSLContext.java` should reveal its
location.

Other HttpClient tests that make use of HTTPS in the 11u test
base should reveal the proper incantation to build it.

best regards,
