install-jdk.sh 2019-04-18 fails for OpenJDK 11

[DanySK]

I am opening a new issue report as the error looks different than the one in #46 and #47.

$ sh install-jdk.sh --target test --feature "11" --license "GPL" --cacerts

Looks like there's problem with https://download.java.net -- did a simple retry work out? According to https://travis-ci.org/sormuras/sormuras.github.io/builds/522042053 all of "integration tests" are green.

Restarted the "integration tests" and the OpenJDK 11 worked out: https://travis-ci.org/sormuras/sormuras.github.io/jobs/522154941
